I wouldn't exactly call 80GB NAS though. I'm looking for more like 800GB of space for simply everything (mainly TV recordings in HD, MP3s, digital pictures etc.). 200GB drives are the sweet spot, so I'm considering going RAID5 with 4 or 5 of them for 600 or 800GB.

Won't be such low power then unless the drives spin down (which is entirely possible) and those EPIA boards usually only have 1 IDE interface, which makes more than two drives a little more complex (i.e. extra IDE/SATA card)
