While this PC is largely uninteresting, at the moment www.accurateit.com has them for $25 shipped. They are coming with 128MB RAM, ~4GB disk, and a CMOS password. I envisioned using this system as a NAS, containing my 250GB disk. Sadly enough, this is currently my largest-capacity disk, and I have it connected to my laptop (my fastest machine, a 2.16GHz Core Duo-based HPQ mobile workstation with Quadro graphics) via USB2. Just making a high-volume data transfer between that disk and my internal drive can raise CPU consumption to as much as ten percent for sustained periods of time (although it's typically more like three to five percent.) While this is pretty minimal, it's entirely senseless. IEEE1394 has much lower overhead and superior throughput, but the connector on my system is tiny and thus annoying.
