Was goofing around and came by this. Not really a hot deal, but cheaper than I've seen them anywhere else (same as the Damn Small Machine on the Damn Small Linux website, except about $80 cheaper), thought some SPCR guys might be interested. Add a thumb drive or CF card and you can have a pretty cheap and compact solid-state system. They even sell low-end 200MHz boxes that are designed to be screwed onto the back of a VESA complaint monitor. Nothing special, but they're only $100.
