This isn't quite a collector's issue, but more of a tinkerer's type of thing. For some reason, I got obsessed with upgrading the old Macs I have laying around my house, and was given money by a friend to upgrade them so he could use one or two. Here is how things stand as of right now... I have the "before" specs listed, followed by the "after" specs. Before: Beige G3 G3 266MHz (O/C'd to 300MHz) 64MB RAM 20GB HD CD-ROM ZIP 2MB internal graphics OS X 10.1 After: Bright Silver Case G4 G4 500MHz 512MB (Possibly 768MB RAM) 60GB HD Superdrive 2x ZIP 32MB PCI Graphics Card (Hopefully 64MB if someone here has one) PCI USB/FireWire HOPEFULLY: PCI Wireless New PRAM battery OS X 10.3 for sure, Hopefully 10.4 if it will work. So, overall, it is taking a pretty old computer and turning it into something pretty nice for someone to use basic iMovie editing with and browse the web. I still need the RAM, Graphics, USB/FireWire and Wireless. Superdrive is still "iffy" as well. Anyone else doing something like this at all? Lets turn this into the "uber upgrade thread!"
