You can pickup a mac mini for the same price as a good G5.
Put it this way I can get a 2GB/250GB Dual G5 Power Mac for 40% the cost of a new MacBook. Or slightly less than a New Mac Mini. I just want it to play with it. TBH a Laptop would suit be better, but it seemed like a bargain.
The 2G/250GB meant RAM/Harddisk.
