Article on how to build your own is
here.
The cooling system (second item from the top) is home-built as well - an article on building it is sitting here waiting to be posted.

The rest is a rather run-of-the-mill stereo and a 1,500VA UPS I bought off eBay for $80 that was in need of a new set of batteries. The whole rack is UPSsed and can run for about an hour without any AC power.
