I retrofitted a "standard" ATX supply to an old Blue and White G3 Mac
a while back - the one problem I found was that the Mac grounded the
pin that ATX used to supply -5V on.  Removing that ground pin from the
Mac motherboard allowed me to use a bog-standard ATX supply.  The Mac
board is now living happily in a beige box.  Camouflage, I guess.
