  1. Why would a computer (specifically a #G4 tower) power off when a DVD is put in the drive? I'm trying to figure out what's happening to the power supply in this situation that's causing the behaviour, because it's probably a pretty good clue as to what I did wrong when I rewired it that's also causing it to turn off after running for 15-20 min.

    And it's not the drive itself. I swapped in another one just to eliminate that variable. I'm fairly certain it's something wrong with the way I rewired the ATX power supply to adapt it to Apple's weird non-standard pinout.
