I am looking at an Apple PowerMac G5 1.6MHZ 1 GB Ram 160GB HD from craigslist. The guy wants $200 for it. He says it turns on, but nothing happens. How much would you pay for a machine like this? What are common causes for this, is it an easy fix? I am looking for a second computer for home use and I want something to play around with and upgrade for fun. I primarily use my Powerbook G4 for work.
