-
12GB（3条4G内存条）1866MHz ECC内存。
-
双AMD FirePro D300 图形处理器，各配备2GB GDDR5 显存。
-
256GB PCIe 闪存。
-

How large would this be compared to a 5 liter barrel? Like this (it's even in black): http://bembel-with-care.de/shop/images/p...
The volume of the new mac pro is around 5.5 liters, so it would probably be very similar.

这是一个奇怪的非苹果式设计：只需滑动锁定开关，我们便可以卸下Mac Pro的外壳。 这里没有顽固的五角螺丝！

我们在这
可乐罐台式计算机中还能找到哪些其他改进的可修复性功能？ 只有时间和翘片会告诉。
Apparently you weren't around for the PowerMac G3 Blue & White or any of the PowerMac G4 models.
Apple has used uncommon screws on Macs. One some MacBook models, the battery is held in place with a tri-wing screw.
Apple's top-tier machines have featured screw-less case entry for almost two decades...nothing new here.
apple cube and G6 etc all featured easy to open chassis

好消息，好消息！ Mac Pro 2013年末的RAM能轻易更换啦。
-
4 GB DDR3L SDRAM（三个，总共12 GB）型号为Elpida EBJ04EG8BFWB-JS-F。
I have read elsewhere (everymac.com and owc) that this machine can actually support up to 128GB of RAM albeit its downclocked to 1066mhz instead of 1866mhz. I've tried 2 different sets of 4x16GB memory sticks in my 12c Mac Pro that were supposedly compatible (one of them being OWC) and both sets result in the machine crashing during sleep. They also intermittently cause the machine not to shutdown or reboot cleanly when doing either from the Apple menu. I also tested both sets with Passmark's Memtest86 v10.2 as well as Apple diagnostics and they tested clean. I ended up taking it to the Apple store and they told me its the RAM as well. Maybe its my particular model, which was manufactured in 2017, but just a heads up for others to stick with a max of 64GB to save yourself some headaches.

只需用T8螺丝刀拧一下，即可轻松地从设备上卸下SSD。
-
在SSD上，我们发现了些老朋友：
-
Samsung S4LN053X01-8030 (ARM) 主控
-
Samsung K4P4G324EB 512 MB 缓存
-
这些硬件组合出来的Mac Pro的SSD看起来和刚更新的MacBook Pro Retina 和MacBook Air非常相似。
-
到目前为止，只有型号的最后几个数字有所不同。 Hmmm...
How do you remove the heatsink/cover from the SSD module? I see several vendors selling blades that are compatible but do not have the heatsink/cover included. I assume one would have to reuse the stock heatsink/cover.
I have the same question. I just pulled a 256gb from mine and to reuse it on a macbook I will need remove the heatsink. I suppose I need to heat with a heat blower but I am not sure...
Hi, is the screwdriver TR8 or T8? I see the Tool on the top of the page is TR8.
The screw is a T8, we listed the T8 as required, we just sell a TR8 as our T8, to account for both T8 and TR8 screws. So if you have a T8 without the security divot, you'll still be able to work on this device =)
Where can I get the 2 Torx T8 security screws from the top right corner of the mac pro? (first picture)

这里只有一个 风扇. Mac Pro的散热由单个风扇负责，该风扇将空气从机箱下方抽入，穿过核心，并从机箱顶部排出。
Can you take that fan assembly to pieces? By a process of elimination, that's where the Wi-Fi and Bluetooth circuitry and at least one of the antennas are.
I agree. Look at the fan power connector, It's a ridiculous connector for a fan. It should also carry data for the wifi module, the 6-antenna array is also integral with the fan, with 1 extra for bluetooth maybe
Tom Chai -
Dominic is correct. The Airport/Bluetooth card and the antennas are housed in the fan area. It is under what is being called the Roof (the black cover in the middle of the fan). It is just adhered by glue, use a couple black sticks to pry it off.
Tom, it is only four antennas. My guess is three for Wi-Fi and one for Bluetooth.
Yes, we can! Check out the update in steps 8-10 to see what we found.
Thank you, Greg. I hope they get the pictures out soon. I saw the airport extereme with 6 antennas, so I assume there will also be 6 antennas in this device. Now the config clears up. As a client device rather than a base station, it doesn't have to work on both bands simultaneously. So the 3 antennas are for 3x3 MIMO wifi, either 2.4G or 5G operation, and an additional 2.4G for Bluetooth. just like iMacs.
According the tear down the fan just lifts off? No screws or anything to unplug? Thats weird.
Is that correct, the fan simply pops off without having to be unscrewed?
ole -
Teardowns are intended to provide a look inside a device, and are not to be followed as disassembly directions. We simplify the procedure down to a general overview, without including every screw or clip, so that we can focus the bigger picture of the device.
Since the teardown, we've made a complete set of guides for the Mac Pro, including a Fan Replacement Guide.
And to answer the question, there are several screws holding the fan in place.
You did not detail the screw removal for the fan from the chassis or the type of torx driver used or the locations of the screws.
You're right, and we don't normally go into that level of detail for a teardown. Teardowns provide a first look at the hardware and an opportunity to assess repairability; they're not intended to be used as instructions. Not to worry, though—we have a complete set of step-by-step guides available for that very reason.

Everybody wants to know if the new Mac Pro can be run on its side or at least tilted (for some kind of rack mounting). If you put the MP back together, can you see if the fan works properly? You mentioned the probability of it being balanced. What happens if it's tilted 45 degrees?
At least one hosting company will be rack-mounting these horizontally. http://www.macstadium.com/blog/new-mac-p...
shamino -
Apple answered my question today with a posting on their website: http://support.apple.com/kb/HT6099?viewl....
It can be put on its side.
As for the MacStadium, I'd rather see the MPs installed within a ring enclosure (like a wine rack) allowing the maximum amount of airflow around them.

-
由于中央散热器是Mac Pro的结构的主导，所以我们最好从它上面拆下零件开始。
-
显卡支架和四颗螺钉将每个AMD FirePro D300图形卡固定。

在与类似的家用台式PC的处理能力和成本比较中，这些图形卡可能是Apple最终在功耗上胜过自制系统的关键。
So have I been being unnecessarily OCD about making sure I don't get thermal paste overflow when I build my PCs? There's a ton of goop in there!
@Joshua Rogers: No. Apple has been applying far too much thermal paste to its systems as a matter of routine for many years-going back to at least 2008. So much, in fact, that people sometimes see a temperature decrease of about 5*C by reapplying the thermal paste on the Macbooks and Macbook pros correctly. Compared to the mess they make in the laptops, those GPUs are actually pretty clean.

256MB = 2Mb
8 bits in a BYTE
In the guide it says
"2 Gb (8 x 2 Gb = 16 Gb = 2 GB)"
It should be
"2 GB (8 x 2 Gb = 16 Gb = 2 GB)"
Corrected, thanks!
Hello, Where can i buy the same GPU in 2018 ? I need to replace because of display problem..
Hello friend, you could try on this website: https://eshop.macsales.com, there are many components and if they do not have it, they will get it.
Miguel -
Try macpalace DOT com for a variety of replacement parts. But be prepared to spend a bundle.

等一下，还有一件事：这两张FirePro显卡有一点点不同。
-
另一个重要的区别是这张卡（并且只有这张卡）带有一个SSD插槽。这看起来像是一个潜在的拓展机会：也许我们可以通过装上两张都带有SSD插槽的显卡来拓展双倍的存储空间？
Would love it know if the dual SSD video card theory is viable. Frankly I don't understand why Apple didn't do this in the first place (not enough PCIe lanes?)
Would like to know as well, I wonder if could swap another similar GPU board from another unit and see if it works.
Wei -
Definitely not possible.
1) Cards differ physically (aside from the SSD). Look at those two holes up top - they are on opposite sides.
2) There are no PCIe lanes left. And even if there were. They would have to be correctly routed to where you need them. As it is even USB 3.0 doesn't have enough lanes (one 2.0 lane for all four ports - so don't count on running multiple bandwidth intensive devices over USB, use Thunderbolt instead). And BIOS would have to play ball with you (which is doubtful).
Martin T -
I meant throughput, obviously.

I happen to have a MacPro on my desk with 1TB SSD and I can confirm that it is just one SSD on the one Graphics card. Not two.

FirePro连接着……额……
-
一个新颖的圆形子板，这块子板把这台电脑所有的模块连接在一起。敲开这些排线之后，我们把整台电脑翻了过来以便深入研究这块子板。
-
由于这块板子上安装了大量难以捉摸的定制接口，我们只能寄希望于板子上的IC可以告诉我们这这块板子的用途。
I think you need to look up the word 'proprietary'... I would bet that those 300 pin connectors are Molex HD Mezz or something similar. Just because it's not a connector you normally see on the outside of a personal computer, it doesn't mean that Apple has made a custom one. The Mac Pro will not be sold in huge numbers - making custom shape PCBs is simple, tooling up to make custom board interconnects is not and is probably not worth it (even for Apple) at these volumes. Get a magnifying glass out, look at the connector and I'm sure you'll see some branding on there that will lead you to the manufacturer.
As Dennis Murphy says, they look like connectors that have been used before.
Technically the circular board with the connectors is a backplane, not a daughter board.
-

-
主板、两块显卡和I/O面板都连接在这一块板子上。

管理如此大量的数据流需要这一群IC们。我们找到了：

旺宏电子（MXIC）25L6406E 64M-BIT CMOS 串行闪存
-
在子板的背面我们发现了和2013中期的MacBook Air一样的980 YFC LM4FS1BH 系统管理控制器
The connectors for the 2 graphics cards do appear to be the same, 10x30 arrays, however the back side of the board clearly shows their respective pin utilizations to be quite different as one might expect. Perhaps a future iteration may go in that direction.

接下来轮到主板了。CPU被一层薄薄的硅脂粘在了散热片上，所以并没有和主板一起被剥离。

在用撬棒撬下CPU之后，我们辨认出了它的型号：
-
四核英特尔至强E5-1620 v2处理器，搭载10MB三级缓存，主频3.7 GHz，最高可睿频到3.9 GHz。

看起来CPU升级是可行的——并且也值得这么做，如果你自行升级到12核处理器，你将会省下将近1050美元。

It will be interesting to see how Apple secures the new Mac Pro to the Apple Store table since they did not add on a Kensington security slot to the computer's body. I suppose the easy nature of how the machine is taken apart makes a Kensington security slot very insecure. Also, if the Mac Pro costs between $5,000 to $10,000, then a thief would easily bring a cable cutter to take the computer away. This makes a Kensington security cable simply very insecure. Thus the lack of security slot on the Mac Pro.
The base of the Mac Pro is one area where some sort of security clamp may be placed - something that is a variant of what can secure the Mac Mini - which also doesn't have a security slot.

At my local shop they had a special ethernet "brick" permanently attached to the networking port. It was only held on by a tiny nylon cord. I guess it works though.

Hi iFixit guys,
Is it possible to connect the video card containing the SSD to either of the two connectors on the round daughter board? If so, then I hope someone gets a second video card with SSD controller to see if both can work at the same time. It would be huge if this machine can handle two SSDs. Of course it may be very expensive...
Hi Andrew, we were hoping the same thing! Unfortunately, the cards have their power connections on opposite sides, so they can only be installed in their initial positions.
I think every PCIe channel is already allocated....
In both our Apple stores in Bristol the Mac Pros aren't bolted down...yet! They are VERY HEAVY though, so anyone attempting to steal one will have a Hernia by the time they reach the front door.
It weighs 11 lbs... So I'm guessing there aren't a lot of gyms in Bristol? ;)
SFZ -
Maybe the in store display version uses a different housing that is made of a heavier material on purpose? That would be odd though
The last generation MacPro is 40 lbs vs this new MacPro is actually lighter... 11 lbs.
Yeah, the old Mac Pro is a hernia inducing item, and a back breaker too.
RobCow -
That might be the most expensive BR2032 ever sold.

No. The US Space shuttle also came free with a very expensive BR2032
How did he remove the io/port board from the psu?
This is a teardown and shouldn't be followed as disassembly instructions. We have a full set of repair guides on the device page, here is the I/O board replacement guide!

我们发现电源模块具有12.1V，27.2A，也就是450瓦的输出。电源模块并没有独立的散热器，而是依赖于系统风扇冷却，使得Mac Pro的噪音只有相当于轻声说话的12分贝。
-
顺便来看一下这个庞大散热片的左侧有什么：扁平的电源线从PSU出发，连接至主板和显卡，并与散热片缠绕在一起。
Oh yeah, great. All solid caps throughout the unit except the PSU. Why o why?
Guess were issues will begin considered the cooling design.
Apple can do better.
Are you the guy that complained about the type of dust caps on a Ferrari Enzo?
I do not see the point. I own old AT SMPS they are about 20 years old now. All of them use electrolytic caps. All of them are running well over thousand of hours. It is not the type of the cap who is running bad. It is the quality. In this case all high quality Nippon.

2013年末款Mac Pro的可维修分数：8/10分（10分代表最容易维修）
-
尽管很复杂，但这些模块化设计却意外的容易拆解。螺丝全部使用了标准的梅花螺丝，很多部件也可以独立地更换。
-
易于打开的外壳便于内存的升级。
-
风扇很容易就可以更换。
-
尽管需要拆解得深入一些，CPU是用户可以自行更换的——这就意味着一些勇敢的人可以自行更换掉基础款处理器并从苹果那里剩下一大笔钱。
-
主机内部没有任何空间和可用的接口用于拓展内部存储。苹果曾经说过希望可以用大量的雷电接口应对这个问题，但是我们更希望能够拥有使用更加广泛的SATA接口。
-
由于使用了一些专有接口和几乎没有余裕的走线设计，在不参考维修指南的情况下就贸然对这台价值3000美元的设备动刀子十分危险。
Whilst widely compatible, SATA is a previous generation technology, support for any storage other than PCIe would be a waste of time in a machine designed to ride out the 4K storm.
There is something like web camera on the port board on the last photo. What is this?

The microcontrollers on the inside of the port panel must be for the illumination that lights up the ports. Somewhere there's a sensor that knows when you're turning the thing around too. Do they use a MEMS sensor for that?
Idk but it will be cool to have a macos function
The connectors shown in Step 8 appear to be identical to the CPU sockets used in the PowerPC G3 & G4 processors. Good connectors, solid, never had an issue with them. No need to reinvent the wheel.
should be hidden inside the fan, packed together with most of the beamforming antenna array and an extra antenna into the I/O housing Apple got really innovative this time, they managed to squeeze everything into this tiny can
Tom Chai -
It is under the Roof, the black cover in the middle of the fan. The card handles Airport and Bluetooth. There are four antennas connected to the card.
Which of these chips have NSA backdoors?
EDIT: All of them apparently.
As usual, a great teardown. Thanks. The Mac Pro is an amazing piece of engineering, Apple did a great job, a work of art. Really nice, only Apple. You don't see hardware like this from other computer makers. I did not see a picture of the flex cables that have the big 300 pin connectors in any of the pictures. I would have thought they would have at least been in the last picture.
I want a USB 2.0 from mac pro because in my lab two devices supported with just USB 2.0
How can get a USB 2.0 from mac pro?
Is there any device convert thunderbolt to USB 2.0 or USB 2.0 HUB
There are 4 USB 3.0 Ports above the 6 Thunderbolt 2 ports on the I/O Panel, and USB 3.0 is fully backwards compatible with USB 2.0 and USB 1.1 in the USB 3.0 Spec. Just plug your hub of choice into one of these four ports.
As an electrical engineering who does circuit design and layout, this is thing of beauty. The industrial designers, EEs, and layout engineers really tried to make the design look very very elegant.
Clever, clever, clever! Now if Apple designers would just apply this same brilliance to make their laptops, particularly the MBA, equally accessible. As a writer, I can't afford gear I can't fix easily. I'm stuck with an aging white MacBook until Apple delivers on that.

The MBA isn't about to get any easier to repair. No way. Despite Al Gore (Mr Environment) being on Apple's board of directors, most of Apple's products are essentially throwaway.
However, if you want a relatively easy to fix Macbook you should grab one of the non-retina 13" Macbook Pros before they're discontinued. I bought one to replace my white Macbook and it's much more powerful. And it's easy to e.g. replace the hard disk.
I probably found who is behind the unknown chip 980 YFC LM4FS1BH.
If you search for LM4FS1 you probably find one of the following manufactures Burr-Brown (BB), Chipcon, GrayChip, NSC (National Semiconductor), Harris (RCA Electronics Pte), all owned by Texas Instruments and Micron, as I did on this web page.
So it looks like it's a special version of a Cost-Effective System Management Controller Chip.
Hope that does help others to get more detailed informations.
Alle the best for 2014.
How does this thing get an 8/10?
"While it will require a bit of digging, the CPU is user-replaceable"
- even a non-proprietary component is difficult to replace
"There is no room, or available port, for adding your own internal storage."
- storage is never enough & yet it ain't upgradeable!
"Apple has addressed this with heaps of Thunderbolt, but we'd personally rather use the more widely compatible SATA ..."
- internal storage not addressed cos Thunderbot is external storage!
- SATA's the idiot proof choice
"With some proprietary new connectors and tight cable routing, working on this $3,000 device without a repair manual could be risky."
- repair manual needed? WTF!
How can anything be considered repairable when proprietary parts of any sort are needed? How can one repair anything without parts?
This should have been at most a 1 or 2 out of 10.
I thought iFixit was the most important thing in recent years to rein manufacturers in. Apparently its caved to and slave to Apple's marketing pressure too!
Oh, I don't know, maybe because you're wrong on almost every point you made?- even a non-proprietary CPU is difficult to replace
Tedious does not mean difficult. Nothing in the teardown implies it is significantly more difficult than most PC MOBOs.
"storage… ain't upgradeable!"
Nonsense! PCIe is NOT proprietary, and anyone, ANYONE can manufacture an upgrade drive.
"internal storage not addressed cos Thunderbot is external storage!"
No, EXPANDABLE storage was addressed, which was the stated issue.
"SATA's the idiot proof choice"
So, this is a pro machine. It is not for idiots. Oh wait, you're referring to…?
Also, you have NO evidence that ANY of the connectors are proprietary. As for repair manual needed, that's the WHOLE POINT OF THIS SITE!!! WTF, indeed.
As for "proprietary parts" care to name a PC that doesn't require such parts?
Mark -
Oh Mark you really have to be my new favourite tech friend :D I love how you have refuted almost every stupid empty unresearched comment here. People just come along and bash Apple with no research or understanding of the cost of the parts. I read on another forum that the D300s are 7870s hahaha. They are actually iirc the W9000 FirePro retailing at 3K+ each. People think that the machine can be competed with, then forget that Xeon is an enterprise class CPU, and compare it to an i7 :P So funny. You made my day :) with your concise and clearly understood evidence. Refreshing
Let's see...the only components replaceable off-the-shelf are the cpu & the ram--or would you add the SSD to that? And you think this merits an 8 out of 10 "repairability score"? As a far as "repairability" goes, if you cannot replace the individual components as needed you cannot repair it. Whether or not you have to tear stuff apart to disassemble it has nothing whatever to do with whether or not it is repairable. Try again. The Mac Pro is actually a 2 out of 10 on the repairability index while it may very well be an 8 out of 10 on the disassembly index--but a "disassembly index" tells us nothing about the ease or lack thereof in its repair (ie, if you can take something apart with thumbscrews but cannot buy replacement components as needed you cannot repair it, can you?)
Sigh. Can't you people at least attempt to find out what you're talking about before you troll?!?
"the only components replaceable off-the-shelf are the cpu & the ram--or would you add the SSD to that?"
Of course you'd add SSD to that. Why on earth not?!? And how about BOTH graphics cards. NOTHING in them is proprietary, and AMD is free to make compatible boards. As to the rest, you have no idea which parts Apple might have available for repairs, such as I/O boards, etc..
Besides which, most issues with circuit level logic are the result of single capacitor or SMD resistors going bad. If you can't replace those yourself, you have no business calling yourself competent at component repair. Try again.
Mark -
"...perhaps higher storage configurations make use of two of this variety, for doubling up on SSDs?"
And where are you going to find the extra 4x PCIe channels?

Maybe varies the pitch (sic) if the fan blades.
The speaker is connected to the I/O board and is shown in the very last picture. Zoom in to find it. There's a two pin connector that connects it to the board and it looks like two screws to secure it. iFixit took the picture of the I/O board with the speaker already removed, but then included it in the final image.

Apple's design is typical Apple consumer bait for an under-powered PC compared to an equivalent PC of the same cost. It is not repairable or upgradeable with generic components, using parts that are either unobtainable by end users or, if they are available, cost a lot more than equivalent PC parts.
The last Mac Pro I owned was the "innovative" liquid cooled G5 which leaked corrosive chemicals that dissolved the innards turning the computer into toxic waste. Fortunately, for me, that didn't happen but its reputation caused that Mac Pro model to plummet to junk bond status in the used Mac market. Like the current Mac Pro, it used proprietary graphics cards which cost a fortune to replace or upgrade. I recently sold it loaded with thousands of dollars worth of still very useful software for the most I could get for it, $150. Fortunately, this Mac Pro isn't liquid cooled. Compare that to the Apple fanatic disparaged PC which cost less for the same capabilities and has a much longer useful life.
You seem to have this thing for posting completely baseless comments with NO evidence to support them whatsoever.
"Apple's design is typical Apple consumer bait for an under-powered PC compared to an equivalent PC of the same cost."
Oh really? Please list the machines capable of handling real time 4k video with similar graphics cards for less than the cost of the Mac Pro. Good luck with that. As soon as you actually bother to do the research, you'll find that just replicating the graphics cards will over flow your budget!
"It is not repairable or upgradeable with generic components."
Please explain how you think it is possible to innovate in a field, and pouch the boundaries back, using "generic components".

What complete and utter nonsense! First, very few machines suffered from leakage issues, and after Apple replaced the LCS system with a Panasonic-fabbed LCS, there were essentially ZERO machines that suffered the problem. Beyond that, you have NO evidence that this issue resulted in used value falling. Please feel free to post a year by year comparison vs OTHER Mac Pros (not just of the G5) that refute this by showing a marked differentiation in depreciation coefficients between machines.

"Like the current Mac Pro, it used proprietary graphics cards"
First, the current Mac Pro does NOT use proprietary cards, it requires special drivers. But you could make that argument of ANY OS. Just because Windows is the defacto standard does not mean its products work without software support. And since the only way to allow Mac Pros to use those cards would be to replicate the Windows 6x driver architecture, which IS proprietary, your point is rather silly and hypocritical.
"I recently sold it loaded with thousands of dollars worth of still very useful software for the most I could get for it, $150."
Leaving aside the fact that it is illegal to sell a machine with preloaded soft are like that without the install disks, your machine is at least SEVEN YEARS OLD. Try giving away your 7yo PC!
"Compare that to the Apple fanatic disparaged PC which cost less for the same capabilities and has a much longer useful life."
Name one.

Just a quick question regarding a 450 watt psu:
As an ex-pc guy who dealt with nothing but 800-1200 watt PSUs, is this really expected to be enough to power for 2 GPUs with 2 processors and 4GB of RAM each, let alone everything else?
I currently have a 27' IMac and I am always amazed at how cool it runs even under full load with graphics apps running full tilt. I know Mac "has a way" with things but even with the 27" Ive always wondered about the PSU and what kind of overhead is available. Fully taxed PSUs seem to not last too long in my experience.
- Dont go hatin' - I even named my dog Mac
In the accompanying video the presenter pointedly states...
"All the available ports have been consolidated onto one card, so if one of your USB or thunderbolt ports goes bad, you'll need to replace all of the ports on your machine, to fix it."
What a strange issue to raise.
A more realistic comment would be that they've split the traditional mother board into a separate processor support board, port board, and interconnect board and cable.
So if one USB port goes bad, you only need to replace all of the ports, rather than all of the ports, CPU support chipset, CPU socket, memory sockets, power regulation, ..... as you would on most other machines.
Or, of course, on either design you could just add some replacement ports via PCIe.
Bluntly, this machine is far less wasteful on component failure than the typical modern motherboard centric machine.

As is typical of Apple's, a replacement Mac Pro IO port board will cost as much as a PC motherboard.
And being that PCs typically have the I/O ON the MOBO, that is about tit for tat, since repairing the I/O would require MOBO replacement, per se.
Besides, you have no idea what the replacements are, anyway.
Troll.

If the cost of replacing the Mac Pro's I/O board is the same or close to what it is for a new PC motherboard, it isn't tit-for-tat because a new PC motherboard replaces virtually all of the computer's components except for memory and the CPU and comes with a new warranty whereas replacing the Mac Pro's I/O board does not, it only replaces a subset of components and the declining or expired Apple Care warranty on the Mac Pro continues. Even if the cost for the replacement for the Mac Pro's I/O board is lower than a PC motherboard, which it probably wouldn't be by much, the replacement of a PC motherboard because of broken I/O port would probably be just the cost of the port connector and a bit of time to open the case, replace the I/O connector (desolder/resolder or unplug/replug) and reassemble the case. Another inexpensive solution available for the PC which is not available for the Mac Pro is to install a PCI expansion card with the I/O ports required/needed.

There were a lot of liquid-cooled G5 Mac Pros which leaked but Apple replaced a small percentage of them, virtually all in the USA only. For its cost, the current Mac Pro underperforms compared to a custom built PC of equal cost - look around the Net at benchmark comparisons and you'll find it. The Graphics cards are proprietary, what other computer uses the type of connectors used on the Mac Pro's - try to buy one. I used to be a Mac Fanatic/Macophile too but I got over it.
Check out this great add on to the Mac Pro Deck! Perfect fit for extra storage capacity: http://www.tuaw.com/2014/09/26/hive73-ma...
Does the circular motherboard reming anyone of the iMac G4? No? Nobody remembers that computer? Nevermind.
For all The Upgraders, upgrade the cpu to Core i7 Extreme 5960X , the GPU can upgrade To the D700,, the sdd is upgradeable , ANd Extra, You can install well WhatEver You Wnat Whit Thunder2, Just pucharse a bizon box and plug on it a Titan X Pascal, Or pucahrse To Bizon box And 2 Titan X Pascal, A extralergue SLI Land, and do a sli.

Hello Dennysb
The problem with thunderbolt 2 : its going through the PCI-2 and not the PCI-3 lanes wich are used for graphic cards so there is a bottleneck.
But the bigger problem either, is that the compatibility are not so simple. Actually connecting an external GPU to a nmp will give you an error code 12 in Windows bootcamp and there is no drivers for pascals cards in iOS for the moment. soon...with sierra
Theoretically you could do " WhatEver You Want " but sadly the true is that the nmp design is quiet "upgrade less" and you have to be a very confirmed programmer, they dont give actually the solution because programmers are fighting : http://forum.netkas.org
Or the other solution could be to adapt the hardware, which is not so clean as software re-programming, but could give the possibility to use the PCI-3 Lanes with only 1 GPU and at least had a 2nd internal PCI based flash storage to the other free PCIe3 such as the new intel ssd.
if you know a solution to really make an oGPU work on nmp tell me :-)
External GPU on Mac Pro 2013 can only use a PCIe 2.0 x4 connection for throughput and the internal GPU cannot be upgraded past D700 because the computer uses the undocumented and proprietary ~300 pin graphics board flex cable connector between the GPUs and CPU. http://www.ifixmaccomputers.com/mac-pro-...
I own the highest-end Mac Pro 2013 configuration and I can tell you its specifications going into 2018 are underwhelming without further upgrades. I had to use a custom-made dongle to upgrade the hard drive to 2 terabytes and 50% faster than Apple’s best offering and I have to reverse engineer the Mac Pro myself to upgrade the internal graphics cards past the D700. The only internal components that are able to be upgraded with 3rd party solutions without reverse-engineering trade secret knowledge internal to Apple is the CPU and the RAM.
I assume, then, that, if my audio output was killed by a ground fault transient (rest of computer works fine) that I should replace the Port board…
I assume that, since ,my sound output was killed by a ground plane transient, I should consider replacing the Port board?
Everything else in the computer works fine.
Does anyone know where the built-in microphone is located and if it is replaceable?
Once again, another iFixit teardown that subtly bashes Apple products for not conforming to their definition of repairability. It is getting tired. And the humor, isn't.

How is an 8 out of 10 Apple Bashing? REALLY??!!!
Aaron Glendenning -
I agree. The ability to add internal storage doesn't make a computer more "repairable". It should be a 9.

@Mojofix: going to have to agree with Aaron, 8/10 on a device packed with proprietary components and connectors seems kind of high actually. Are you just upset that they put the word "inexpensively" in quotes?

PC repair should not require a putty knife. Most Apple products are built like consumer toys that will be thrown on the scrapheap as soon as the new model comes out.
The fact that a Mac Pro can be repaired is not something that should trigger any special praise. These machines have always been different from Apple's other products. People should expect better of them. It's good that the new Pro is as repairable despite their proprietary parts. However, it's just what should be expected.

"PC repair should not require a putty knife."
Who says?
And being that this is not required here, WTH is even your point?
"Most Apple products are built like consumer toys that will be thrown on the scrapheap as soon as the new model comes out."
Um, apparently you have never checked the Mac resale market.
You simply have no idea what you're talking about. At all.
