As some of you may have read I was going to get a PowerMac G4 and turn it into a PVR, well I am no longer doing that because I could get a TIVO with a DVD burner for half the price. So anyway I want to get an older G4 PowerMac so that I can upgrade the processor,RAM,hard drive,video card, add USB2.0, add SuperDrive,etc. I just want to do this as a little project so that I have something to do with my time, plus I have never done anything other than upgrading RAM in a Mac and I would like to try and do some things. Does anyone have any suggestions on what PowerMac G4 would be the "easiest" to upgrade and where I could get the parts to be able to do this. I look around the 'net and found some places that sell the parts but was confused when they said about what model I would be upgrading. I would be taking this up to at least a 1GHZ processor and 1GB RAM.
