I've wanted a G5 quad for almost 10 years now and was about to give up my search for one (here in Ireland they are particularly hard to find at a reasonable price). I have come across one for €150 however the seller says it doesn't boot, when he powers it up there is a click and nothing more. He thinks it is one of the CPUs and so will include a known working CPU. From what I've read I would lean towards the PSU being at fault rather than the CPU. So I guess my question is should I take a chance and get it and try checking the PSU for correct voltages etc or leave it alone and go for either a quad at normal price (€300) or maybe a DC or DP model?
