So, I've started collecting PPC Macs, and my hunt is still going. So, I often check Marktplaats within my area for Apple computers. I recently found a Power Mac G4 MDD with the original Apple monitor for €20, unknown specs, and a Quicksilver with a 800MHz processor, 700MB RAM and a 120GB HDD for €10. Very decent prices, but I want to know I don't get a lemon. Does anyone have any tips on things I should watch out for?
