How do I know the PSU is dead?I see some cross posting on this forum about the 3 screw removal option but mine wasn't that, I had to go in the back,...
Answer to "Computer will not turn on"If you are handy with tools and careful you can disassemble this beast but know that it is not a general user repair. The guide on this site works quite well, you'll need to add in a bit of the HDD removal so you can fish out a cable but it does just fine. If you are not handy then I priced out the repair from a Mac repair guy in town and it would have run $180 in labor, and then the PSU costs. For that you can pretty much score a working newer model on eBay. At the very least you might want to open it to get your HDD out. My worry is not the disassembly, but the reassembly.
