Phoronix recently built a server farm and bar, a perfect use for a basement.  In building the server farm they learned quite a bit about the process of creating your own server farm as well as the costs involved.  For instance their power bill has gone up somewhat, including the air conditioning they are seeing usage of 3,000 kWh a month so you might want to do some calculations before setting up your own.  Take a look at how the mostly finished design worked out and if you are interested you can find a link to the original article covering the build on the last page. 

"It's been just over six months since I completed construction on the large 60+ system server room where a ton of Linux benchmarking takes place just not for Phoronix.com but also the new LinuxBenchmarking.com daily performance tracking initiative and testing and development around our Phoronix Test Suite, Phoromatic, and OpenBenchmarking.org software. Here's a look back, a few recommendations to reiterate for those aspiring to turn their cellar into a server farm, and a few things I'd do differently next time around."
