Although this is a protoype, the box steam sells next years should look somewhat similar.
From the article.

Take a good hard look at Valve's Steam Machine, because it's the last time you'll see it. Er, something like that. Only 300 of the metal beast above will ship to beta testers, and then Valve says it's cutting off its own supply of Steam Machines. "We're really building this as a test platform, and there are many machines that are gonna be made by third-parties. They're the ones that will be available commercially in 2014," Valve designer Greg Coomer told Engadget.
