My mom randomly decided she wants to buy a MacBook Pro 17" to replace her 17" PowerBook G4, which was one of the original 1ghz kind (she bought it the month it came out in 2003). So that PowerBook G4 is now going to me and I'm pretty psyched as my last 17" PowerBook was stolen and I've been using this 350mhz G4 AGP tower for a while. I know very little about this machine as I never paid much attention to it since she originally bought it. Some Qs SATA or IDE? Maximum RAM? Any sort of processor upgrade or overclock options? How good/bad is the GeForce 440? I don't play games. There are some lighter areas on the aluminum case that I wasn't able to clean off today. They almost look like stains, but in a weird discolored sort of way. Usually stains are darker than the material they are staining, but these splotches are a lighter color than the rest of the aluminum. Any ideas?
