Water-cooled ATI Tech Station Rig
It is the HSPC Tech Station (larger version). The smaller one didn't have room for me to tack on extra goodies should I need another pump, res, HDD rack, fans, etc.
Solidly built and super-easy to mod. The decks are a sturdy plastic, but you can drill through them like butter. It also comes with a set of tiny flexible switches and lights to hook on for your "front panel" buttons like power, reset, HDD LED, etc. Oh... and an antistatic/antislip mat for the bottom. I ended up velcroing the rad and PSU on anyhow. I did drill a hole to fasten the pump mount down, though.
