My most recent incarnation of my Gaming HTPC (aka my SteamBox). It pretty much consists of everything handed down from my old Gaming Rig just stuffed into a pretty Silverstone HTPC Case. It is pretty much always under construction but i think this will be here to stay for a bit. The only dedicated brand new part is the MSI Twin FrozrIII 7950 3gb since its main purpose is gaming on 120" Screen in my Home Theater. After adding the 7950 I am now debating on a Lian-Li case for better cooling but overall I am very pleased with my results since I only need 1080p.
