Hey all - Just came upon an old PowerMac G4. I don't have a monitor to connect to to yet, so I'm not sure what speed the processor is and such. (The model # is M8570 if that helps anyone...) Anyways, I was wondering if it's possible and how difficult it would be to upgrade this machine with a new processor and video card. Also, I know these old Macs can only handle up to a gig of RAM. Is there any way to expand that capability (I've got a bunch of 1 gig sticks of RAM that need a home). Any help/suggestions would be much appreciated. Thanks.
