Since the lovely people at WeLoveMacs are of absolutely no help (curses and swears at them in 3 languages), is there any way i can get the dimensions for the G5 power supply? I am wondering if i can possibly mod one to go into a G4 tower giving it 600W of power instead of a measly Quicksilver 344W or MDD 400W.

The mod will be done to a Quicksilver G4 but i want more power for the amount of peripherals going into it.
