I have the dual processor it will no longer turn on. What happened was my mouse and keyboard froze so i did i hard restart on the cpu and it never turned on again.. I went to apple they said if its the logic board then its about 800+ to fix.. if its just the power supply 250 or so.. i found the parts online for cheaper, but before i order anything I would like your feedback...

Also In regards to actually getting to the power supply how do i do it?.. The processor has to come out im guessing and is covered by a aluminum shield.. The older G5's came out simply by pressing underneath the corners.. Im going insane searching the web only to find outdated guides..

IF ANYONE CAN HELP ME FIND A DISASSEMBLEY GUIDE THAT IS UP TO DATE I WOULD BE VERY APPRECIATIVE!
