I've got an old power mac G4 laying around, and have'nt used it in forever. I've got another desktop that i use mostly. Im wanting a laptop though, and figured i would try to sell this G4 or trade it for a laptop. But i have no idea and have some questions. Is it even worth trying to sell or trade it? If so how much would be a fair price? It's the one with the "Quicksilver" case. Thanks for any help.
