I'm still just laying mine on my desk...is that bad?
For a case, I just grabbed a small 1U case from the as-is pile at the local electronics recycler. Used to be an Internet firewall in a past life, but no longer works. It only cost me $3, and has a nice power supply in it already. It is steel, so it's not exactly easy to work with, but I have a pretty well-equipped shop.
