Re:How about a Linksys router or D-Link NAS box (Score 1)

Another option is the Linksys NSLU2, if you can find one used. Lots of community support for this device available here: http://www.nslu2-linux.org/ I've been running one since 2005 with the Unslung firmware, but I recently upgraded it to a standard Debian 5 install and it's working better than ever. It's not as fast as the newer NAS devices, but then again it draws less power because of it.
