   G4 "Sawtooth" - 350-450MHz, 100Mb ethernet, AGP video - can use a 
standard ATX PSU with a simple -wire-wire modification.  The other G4 
PSUs *look*, standard, but they definitely aren't.  The Digital Audio 
model requires a 28V supply line....

   I don't recall whether a G3 will boot with a dead battery or not, but 
I'm fairly sure it won't boot with no battery.
