It uses a slot for power, but that's it. Might be worth checking into, as the tester at the magazine said it handled everything he threw at it. Note it is IDE only, not SCSI. It was about $250 as I recall. I will try to find the URL for it, but it was just reviewed in one of the popular PC mag's online.
