Mac G4 PSU dead

[pimpdriver]

The PSU on our G4 Quicksilver powermac has died, well I think it has, it stays on for about 5 minutes then turns itself off. Everything works well beforehand however.

It is over 7 years old so has had a good run so far (far far longer than a PC would have lasted without upgrading everything twice, like Trigger's broom........).

Anybody know:

can you fit a PC PSU with a link cable as some of the pins are slightly different?

Where I can get a 2nd hand one (tried ebay so far).

Can I take out the hard disc (40GB) and put it into some kind of caddy so I can copy the data off it???

Cheers

Steve
