Hi

Very difficult to find the exact size of the bit for the screwdriver. And it is very tight to unscrew one of the screws.

Maybe I had spoiled the head of the screw.

What is the solution?

Thank you in advance.

Michel

missing a very crucial step before step 6. if you don't remove the cover (where cd rom is) and unplug the PSU cable, you'll damage something.

for screws, 2.5mm didn't work for me, but i used a 3/32 hex with ball end, and at an angle, it will loosen screws.

Doesn't work for a micron. Step 6 is impossible. Can't get the power supply out of its place more than a few centimeters. The side closest to the backplate of the casing can't come up only some millimeters, while also the fixed!! power cord is a serious obstruction.

Moreover there are nowhere cover plates left, so this is not a comparable situation as described in step 7.

My last remark should be forgotten. The power cord has been connected to the Mac pro to give the impression that it's mounted fixedly to the power supply. But if you pull with very much force (an attempt of despair), it then again appears to be a 3-hole connector like is the case for common computers. If you don't know these systems, this is very treacherous.
