So my latest insane attempt at building yet another Mac is taking the logic board from a 1.25Ghz G4 iMac (the 20" screen one) and placing it in either a PC case or a gutted Digital Audio case. I have all the info I need for the project except how to hookup an ATX power supply to this puppy, if that would even be possible. I don't have any other parts from the iMac as I bought the board all on its own and have gathered other needed parts as I come across them (VGA converter etc.) but don't want to shell out another $130+ for a stock power supply as that would bring the total cost too high. Anyone have any ideas, or even the pinout for the iMac's power supply so I could fool with it myself?
