3RSystem M-Station HT-1000 HTPC Chassis
 

The case itself is very attractive to the eye, and designed to fit in with your existing A/V gear; something it manages with aplomb. Available in three colours, the silver model we chose fits in perfectly with its surroundings. Hardware installation needs to be thought out a little but there were no real 'gotchas' caused by the case itself. No sharp edges either, allowing for a pain free installation. The HT-1000 supports both ATX and mATX motherboards and has provision for a full ATX PSU, allowing you to build a high powered system, perhaps for some large screen gaming.
