My 2.5 GHz dual G5 had a single processor die. It's fairly stable until it warms up, at which point it crashes hard. I suspect that if I can get into the processor module and disconnect the power from the flaky processor that the machine will run fine (albeit slow). I'd like to do this so I can limp along until the updated iMacs come out, at which time I'll replace it. I can't find any disassembly instructions on the web for the liquid-cooled G5s. There was a thread on MacAch ( here) but the linked site is dead. The popular Sharpening Beneath disassembly isn't for liquid-cooled machines. For the life of me I can't figure out how to do it short of completely disassembling the case and removing the motherboard. That may be the only way to do it, in which case I'll probably change my mind on doing this. I'm hoping someone here has access to the actual tech instructions. Any help is appreciated, and PM me if that's easier.
