I am looking to buy a used G4 Dual 1ghz M8667LL/A and use it as a file server. What is the max amount of hard drives the stock power supply can power? My plan is to have one internal as a boot drive then use a ESATA PCI card to power and external enclosure. The external enclosure will have 8 or so HDs and use a port multiplier to have one ESATA out to the G4. Is this computer capable and or powerful enough? I guess my main concern will be finding a ESATA card compatible with this computer. Thanks Also, does anyone know of a power supply that can power multiple HDs without needing a motherboard?
