I'm missing unboxing step what is inside etc.

Thanks for nice work !

Brilliant teardown. Couple of points;

1. Is there a "spare" SATA connector, and what would it take to add an external port ? From your earlier posting I think there's room on the back panel.

2. Cable management - and this has always been a bugbear on the whole iMac range - why not cut a slot in the stand to feed all cables through for neatness ?

3. Have you tested the HDMI input, and what does it look like ? Would you watch TV on this with the addition of a USB tuner ?

4. Let's see it go back together...:-)

Seriously, fantastic teardown. I showed the Mrs and she hit me, yelling NO, NO... go figure...

Hi brothers,

I too am wondering if an eSATA port can somehow be added. To me, that's the biggest thing that's missing from the latest Macs. I've heard about the forthcoming Apple/Intel Light Peak optical interface but nothing is going to beat native SATA for an external storage interface (no bridge/translation necessary).

Yep! There it is! Bigger, wider and brighter!

This iMac came with 2x2GB chips.

Is this the complete step for accessing the RAM space to add more RAM? (I plan to add 2x2GB more.) That is, just open the access door and there it is?

Yup, just remove the access door and pull the black plastic strip attached to each RAM tray away from the bottom edge of the iMac to eject the chips.

Could we replace the original edge-to-edge glass for a Multi-Touch model?!?! Would it be a possible mockup?!?! It would be very nice in Business Shows to present de digital leaflet and keynotes. And at home to be just set it as enormous "tablet". the point is how to make it for a low price?

hi!

how is the glas mounted on the enclosure? only by magnets? is it real glas or perspex? thanks for your answer!

Hi can you describe better how the glass attaches to the frame. Is the black border on the glass metallic so it can be supported by the magnets. Thanks.

Im pretty sure its real glass and yes it is only held in place by magnets

I own a 27" iMac that has this edge-to-edge glass broken at left side.

Monitor is still intact. I cant exactly understand how to remove this surrounding glass.

Do i need to use the suction cups on the surrounding glass so to remove it from the magnets? Cause on the photo the cups are placed on the Monitor..

There have been a number of reports on the Apple forums of the glass being broken on the bottom left side. If you have an Apple store nearby, you can ask them to replace the glass (they will have to get the replacement glass shipped to the store), otherwise call Apple support to obtain a replacement machine.

Actually, in both photos the suction cups are attached to the glass. The display is recessed about .125" below the glass panel, and the two components are not connected. To remove the glass, lay your iMac stand-side down on a table. Stick two suction cups along the top edge of the glass and pull it away from the rear case of the iMac. Rotate the top edge of the glass panel slightly away from the rear case of the iMac to clear the mounting pins, then slide the glass toward the top edge of the iMac to free the flat tabs along its lower edge.

Is the LCD itself glossy, or just the glass? I am considering getting a 27" iMac but hate the glossy display -- would it be feasible to run it with the glass removed? Maybe sealing the edges with some carefully-placed electrical tape or something...

Strangely I found that reinstalling the 8 screws to keep the LCD panel in place my T-10 torx kept demagnetizing. (I only have a slight magnetization in place to keep the screws from falling inside)

I keep my tools stuck to a voice coil magnet I pulled from a 3.5" hard disk. I haven't had a problem of screwdriver being *too* magnetized, so far.

24" iMacs had matte displays (model identifier iMac6,1) when first introduced (all white)...one of two reasons I haven't upgrade my 6 24"iMacs.

The other reason Bluetooth full size keyboards (model A1016, white) are only available today with a USB cord. I don't have the specs on the new cabinet width, but the 24" iMac: is nearly 23" wide. A 17" wide, full size keyboard is too big to put in front of a 27" iMac?

Progress?

I agree on the lack of a numerical pad--disappointing. I wonder how long until someone does an indepth review of that display? LED IPS displays are $$$ especially if this one renders color as well as some of the other high displays. That makes the price of this machine so much more reasonable.

LED Display - is it RGB LED? Is it side lit or back lit?

来自 wkchan 的话:

RGB LCD with LED backlight. It is not an OLED display, which is a common source of confusion (OLED vs LCD, LED backlight vs CCFL).

来自 Diggsby 的话:

RGB LCD with LED backlight. It is not an OLED display, which is a common source of confusion (OLED vs LCD, LED backlight vs CCFL).

Hmmm ... my origin question was not too clear.

I meant to ask:

1. if the LED backlight uses "RGB/tri-color" LEDs or just "white" LEDs (as in the MacBooks).

2. if the LED backlight on the edge of the display or the back of the display.

LG makes a 1920x1200 17.1" LCD panel, LGD01b3, with RGB LED backlight, edge-lit. The LGD01b3 display has a wide color gamut, high contrast with vivid colors but suffers from non-even backlight color (I call it "wild gamut" because I can never get the color profiling right).

Cannot find any info on this LM270WQ1 LCD panel and was hoping that the Teardown guys can tell if the backlight uses RGB LEDs and if the panel was edge-lit.

This LCD panel is IPS and if it also uses RGB LED, then the iMac 27" is really a price break through!

But on second thought, went through the specs and never see "wide gamut" being mentioned -- so likely at this price point, it is likely just a white-LED backlight.

Please disregard the previous question. I just don't know enough about monitors and I dread buying a Mac with a glossy screen.

I'm also interested in an answer to wkchan's question regarding whether the imac is backlit by white or tri-color LED's. Thanks!

OK, I still don't think we have a definitive answer as to how the new displays are actually "lit". Has it been confirmed whether the screens are edge-lit or back-lit?

Also, regarding some recent display anomalies... I've been involved in a few discussions over at Ars Technica [URL=http://arstechnica.com/apple/news/2009/1...]here[/URL] and [URL=http://episteme.arstechnica.com/eve/foru...]here[/URL].

So, this iMac won't become a decent second display if the logic board goes south, or after quad 2.66GHzs are no longer "fast enough" to read email on?

Isn´t it possible to make a mDP "HUB" by the DisplayPort connector shown on this picture?

With a bit of work, that would make a great desktop image

Hey, I am still a Big Mac!!! Don´t mess with me. My brother mini, doesn´t have a display and no body cares ;P

I'm quite irritated with Apple for not providing a slot for a second 3.5" drive. They're the masters of Tight Squeezes; they clearly could have shuffled things around slightly more to add a second drive bay.

A gorgeous media computer like this simply craves twin terabyte drives running in RAID.

I noticed that the picture doesn't show any Kapton tape on either end of the Airport cable. Is that the way the iMac came or was the tape removed before the picture was taken?

You say that there isn't room for another drive; does that also go for 2.5" SSDs? Are there extra SATA ports on the logic board for more than the single drive anyway?

If i install a SSD instead of the optical drive, could i boot up OSX from the SSD and use the internal 3,5 HDD for media Stuff?

You could fairly easily replace the optical drive with a 2.5" hard drive or SSD. We sell an enclosure that enables you to install a SATA drive instead of the optical drive. There are no extra available internal ports that we noticed.

That should work just fine. You would just select the SSD in Startup Disk as soon as you get the drive in there with OS X installed.

What model WD 1TB is this one? the Caviar Black or the RE4 model?

来自 joe 的话:

There should be a 3.5" drive with both an SSD and a high capacity HDD on it (dual SATA). The SSD wouldn't need to be that big, say 32 or 64GB , since the most active files and swap space would reside there. I guess it would only apply to the iMac though.

Given how much the SSD in my MBP has sped things up, I almost feel installing an SSD in a new iMac is a necessity.

You would have to downgrade the internal Hard Disk to less than the size of the optical bay HD or use the optical bay HD as the boot drive for Time Machine backups.

The Time Machine backup disk must always be larger than the disk it backs up from, AFAIR.

I'd like to try the following:

SATA 1: 120GB OCZ Vertex SSD

SATA 2-> port multiplier

1: 120GB OCZ Vertex SSD

2: SATA to eSATA and thread out cable from iMAC

Then put the SSDs in software RAID 0 and still have a nice eSATA port coming out...

Of course this would require the SATA controller to support port multipliers, any idea what chipset it is??

HI, is there any heating sensor will have to be disabled, if I replace the optial drive with SSD. I notice someone replace the HDD with SSD, then the heating sys reports error and the fans go nuts. So how about optial drive, the same?

Apple added a build-to-order option for a 256GB SSD in the 2010 iMacs, and you can have both the SSD and a 1- or 2-TB hard drive. Anyone know where the SSD goes? Can you buy a 2010 iMac without an SSD and add one yourself?

This article was written about the "Late 2009" edition. The Mid 2010 update now has the option for both a Serial ATA Drive + a Solid State Drive. How do both of these drives fit into the enclosure? Has there been substantial changes to the internals to allow this? Can you add the second after purchase?

Why did you ignore the Electrolytic Capacitors and their values?

These caps are the components most prone to failure.

This is especially true of PS built in the latter part of the 2000 decade. Somewhere around 2006 - 2008 the electrolytic capacitor supply chain was flooded with caps with a built-in failure mechanism due to being made with incomplete data from industrial espionage gone wrong. My Late 2009 iMac PS failed and its capacitors showed the physical signs of this failure mechanism. Replacing caps is easy and cheap. I had a VISIO Television that had the bad caps and failed. It cost $15 to repair a TV that originally cost just under $1,000.

Also where are the screw points for the dissasembly. all I see is "a couple of screws later" what is that!?

I think they were just a bit lazy with the measurements here.. look at the image of the superdrive and google the code. I'm pretty sure that it is actualy a 12.7, not .5 (i've NEVER seen a 12.5 drive.. anywhere), so it will be a perfect fit.

I recommend the UJ-235A over the 135 they mention in the article too, as it can burn blu-ray discs at 4x.

If it's anything like the original Macbook Pros, which I used to be a technician for, they wrapped the antennae cables around the edges of the screen. Since those screens are now 100% glass, I wouldn't be surprised if they left the wires there since it's the only part of the system not made of aluminum!

Yes, it is/was a beauty to behold, but that was largely due to the fact that there were several "user installable" parts. For example, midplane board, hard drive, RAM, etc. Funny thing is that people still needed help simply installing RAM! Apple rethought this strategy, because subsequent iMac models did away with this clean internal design (and so many user-installable parts).

来自 Jeremy D 的话:

I'll take that flame bait, but not hook, line and sinker...

First of all, you must be easily amazed, because Apple has always had higher premiums on their components. They can only leverage their monopoly on stuff like NAND flash memory prices.

Not a "magic" WD hard drive, but neither are the Seagate drives (their other drive supplier). Apple generally maintains more strict product tolerances from vendor for things like RAM latency, hard disk burn-in and MTBF. This usually means Apple staff "qualifies" goods before getting them into your hands. This adds to cost--esp if Apple has their own special recipe of firmware to drop onto drives (e.g. server-grade drives).

@Chris - the intent of my post was to take the pi$$ out of what appeared (to me) to be Mac flame-bait from. "Mac zealot" was a self-depricating reference to steal Joe C's "thunder" if/when using said term himself.

The point is that life is not as black and white as "I'm a Mac"/"I'm a PC"--as Joe C insightfully points out in his later post re: "PC" definition. Apple's and Microsoft's ad campaigns try to stoke this outmoded argument. We know how common it is for people to work on Windows PC at the office and Macs at home.

But "PC" statistically refers to Windows PCs (given the slight market share Linux has).

(Reasonably) technically savvy users reading/posting to this site should be somewhat aware of how versatile, lightweight and supported different flavors of Linux can be--compared to Macs and/or Windows PCs.

Nevermind . . . this a waste of everyone's time. Sorry for the trivial distraction. Thanks Joe C. Happy New Year.

OK so duh on the processor so let change that to 2.93ghz i7 and the 4870 x2 video card

Come on guys, show us what's under the heatsinks, that would be great, i want to upgrade my cpu, but i want to see it first

Is it possible to drop in a quad core later? I am thinking about getting this one and dropping in the quad later when I have the money.

Oh, a wonderful idea! I'd love to see the iFixit folks give this a try and report on the change in performance. Then they could sell us the proper CPU and provide the instructions for accomplishing the task.

Does anyone know if there are any mainboard (off the video card) graphics chips (e.g., scaler), or are the DisplayPort signals routed directly from the GPU to the LCD panel and DisplayPort connector?

Concerning C2D Quad-core replacements:

After looking at the CPU specs in detail for the E7600 and E8600 C2D parts and comparing them to the various available C2Q parts, it seems to require one of the 45nm QxxxxS parts to even have a chance of working, with the Q9505S or Q9550S being the most likely of the higher-end ones. The power regulator specs/etc. are different for the non-S parts.

I'd be happy to try it, pretty sure the worst thing that will happen is that it won't boot due to lack of C2E (Stop-Grant) support or confusion about having 4 cores instead of 2. It could also come up but refuse to recognize the other 2 cores.

Hmm. Is a Q9550S CPU the only thing that you are lacking?

Hi is it possible to replace the USB ports on this Mac? I have 2 dead out of 4 and its driving me crazy!!

Sorry, but those "front" and "back" links are dead. Please update with new links. Those are very important photos. Thanks.

it's possible to remove graphic card and replace it with the same but 512mb vram?

Please add pictures with the heatsinks removed both for the GPU and the Logic Board

So is that still a laptop card, or like the proc, are we getting desktop class cards now?

I agree! You never take the heatsinks off! Come on!

What's the name of that supposedly standardized slot? I've only ever seen Apple use it; I recall it was the same in the previous two revisions as well.

AXIOM (ATI) respectively MXM (NVIDIA). IF Apple uses that (do they?)

I don't get it. On this model you can change the graphic card?

so is it possible to replace graphic card in any 27 inch imac?

i was rly sad when i have seen that 512mb card in i7 model

Does anyone know what size the counter-sunk screw are securing the GPU heatsink? I snapped one over the weekend doing a teardown to redo the thermal paste.

Thoughts on what you do if the case for the Pram battery gets disconnected slightly?

hi efi chip???
