Need a cheap file server, Linux machine, or emailing machine? How about a refurbished 700MHz Celeron for $47.91. It's really bare-bones, with only 128MB of RAM, a 10GB hard drive, Windows 2000 (not installed), onboard Video and Audio, two PCI slots, one AGP slot, and four USB slots. Not bad for $47 though.
