I used to have an emac 700mhz i was even able to run leopard on it, the only thing though is that they are loud and most of them pre 1ghz use usb 1.1 which is painfully slow. They do have the faster firewire but as most components now days are USB, it hardly helps. I would not get one unless it was at least 1ghz w/ usb 2.0, but be careful as there are two versions of the 1ghz one with usb 1.1 and one with 2.0. Also you might just be better off waiting for a better deal i got my 17" imac g4 with 1gb RAM 80gb hard drive, and super drive for $249
