Having just upgraded my home server to a rack mount version, I have my near mint condition fanless CV860A for sale.

Complete with 512MB of Low Profile RAM, all you need to add for a working machine is a 2.5in hard drive, Compact Flash Card, or DOC (Disk-on-Chip).

This machine has proved perfectly capable of running several different flavours of Linux (where it was operating as an IMAP, web, domain, print, and file server for my household), as well as giving me a fall-back position of being powerful enough to run Windows Server 2003.
