I've recently found a Powermac G5 for sale with a few problems. I think if I can get the price down, I may try my hand at fixing it up. The owner says he thinks it was in a lightning strike and now it doesn't work. He told me the power supply fans come on and motherboard lights up, power light comes on when you push the button to turn it on. Do you guys think this could be as simple as a PMU or PRAM reset issue? Or does this sound like a fried motherboard. I don't want to buy it if I am going to have to replace a bunch of parts. I figure I can fix just about any Mac, but if something is REALLY beyond repair and needs replacements I don't want to waste my money.
