One power supply running the hard drives, CD and floppy, another running the motherboard.
I had two small power supplies, one larger computer which I thought might be starved for power. So, give a fool enough different plugs and receptacles and sooner or later it's going to be well nigh irresistible.
(Car and Driver magazine years and years ago was reviewing a British car, I don't remember which one. The header was, "Give an Englishman a piece of sheet metal and he will do something stupid with it." Similar syndrome, I'm afraid.)
