I recently bought an IBM thin client machine on eBay. Very nice piece of kit. The plan is to stick the jet engine-sounding machine in a cupboard and use the thin client as the actual desktop. Depends on the video playback performance though, really.
So I bought a USB keyboard and mouse adapter, because this beastie only has USB. Works a charm.
Next step is to install an OS on the CF card and attempt to boot it.
