Someone in town is selling this for $195 : Apple G4 dual processor 533 mhz tower computer. Comes with OSX 10.1 and 256 MB of ram. Comes with flat screen apple monitor, pro keyboard and mouse. Assuming it works, is this a good deal ? Were these machines prone to breakdowns ? I was thinking about a mini Mac, is this thing faster or slower than a CoreDuo mini Mac with the superdrive ? I would want to up the memory to maybe 1GB, how much would that be for this machine ?
