The purpose is to have an unRAID box capable of running SAB/SB/CP and Plex Media Server. I have an Acer Revo 1600 running XBMC Live that I've been using for many years now and it plays everything I throw at it quite well. The Revo has always had 2 external USB drives hooked up to it, holding my media. No redundancy! Luckily never had a drive failure.
Thanks to eskro's helpful threads (on the XBMC forums), I settled on creating a SFF unraid box similar to his guide.

I picked the Lian Li Q25B case because it has a SATA backplane. Additionally for the coolness factor. In my teenage years, I built a couple Shuttle-based SFF computers so I'm used to working with little space! I'll outline this thread as I complete the build. I'd love to hear feedback, as well!
