If I had the extra money I would buy this in a heartbeat, pretty good price if all is ok with it.
The DA G4 is very versitile little machine, can run OS 9 and 10 natively. I have preview OS running on it very nicely at 533MHz.
I would upgrade the RAM to a Gig and maybe even get a better video card and even through a 250GB IDE drive in it with a super drive too! BTW if you are near BogusBuy, er, Bestbuy you can pick up a Phillips Superdrive for $39, NEW!
