I have the possibility to buy a PowerMac G5. There's 'only' 1 problem with it: it refuses to boot. The problems started with the fans spinning louder then usual, then trouble when booting (with up to 20 tries before it actually working), now it is completely lifeless. I'd be able to buy it for 125 (+- $175) and I'm not sure if it is 'worth' it. After Googling I found out that its a common problem for the G5, with 'not too great' power supplies, for instance. But I'm not sure the PSU is the problem in this case. Shall I take the risk or look elsewhere? System specs: (2005) G5 2GHz, 3GB, GeForce FX5200.
