Connected to the server room was also the bathroom, redone in this process. Besides making the wife happier, it's great with having the bar and meeting table just a few steps away.
All of these systems are now controlled via the Phoronix Test Suite's Phoromatic for automatically powering on/off systems when needed, scheduling of benchmarks when new code is available to test, etc. The projector is great for making it a "command center" to see the real-time status of benchmarking across the systems.
There's still a few more systems I need to rack as well as a few other monitors I still need to setup in this basement server room.
