Power Mac G3 Service Manual
Introduction
The Powermac G3, apple's G3 Powerhouse. This computer Introduced the design that stuck until the powermac G5, but this computer started the 'Handle's' Trend, every powermac G3, G4, G5, and Mac Pro now has handles. This computer boasted a 350Mhz, 400Mhz, and 450Mhz PowerPC G3 CPU. This cpu is incredibly easy to overclock, due to it's 'clock-config' jumper convienlently located next to the CPU(though i don't encourage overclocking). This computer had blue plastic, resembelent of the iMac G3's and the iBook G3 Clamshells. It would have been great if Apple had made this is other colors, like the imac, a lime green Powermac G3 would rock!

Removing the power supply
Disconnect the power connector from the logic board (this looks alot like a standard ATX connector. The lone difference is that the wire which supplies -5V on an ATX supply [pin 18] becomes a ground wire in the B&W G3. If you just plug in an ATX supply without any modifications, you'll short out its -5V output. )
There is a 4-Pin Cable connected to the front panel box, remove it.
Disconnect the internal fan cable.
The Fan Connector
Then Route all of the cables up through the case to the level of the power supply.
Remove these phillips screws.
Now, you can slide the power supply towards you, and remove it.

Also remove all 3 hex screws from the rear of the case located around the power connectors. Only then, will the PS 'just slide out.'
