It wasn't too long ago that Valve unveiled Steam Machines along with SteamOS, both of which were methods for Valve to break into the living room which is currently dominated by the likes of Sony's PlayStation, Microsoft's Xbox, and Nintendo's Wii platforms. While Valve has yet to release Steam Machines to the masses, they did share what a prototype Steam Machine might be like and given those specifications, building such a machine for yourself could cost anywhere between $700-$1,800, money which technically could be put towards building an awesome gaming PC for yourself.
