I personaly have a power mac G4 (dual silver door) 1.25 dual CPU 2 gigs of memory, 200 gig main, 80 gig back up, Ati video card.
I have a coupple of these machines! I also have parts around! IDE be more then happy to show anyone how to change memory, add 3 CPUs change drives and more! Even cleaning the plastic cases for studio displays and towers!
I'll be adding links for taking them down to the boards, up to the drives! Memory, and modding!
