Steam Machine REVEALED! – Inside Gaming Daily

The prototype, which will be sent out to 300 eligible Steam users later this year, is described in a new Steam Universe announcement as a “high-end, high-performance box.” It’s being built entirely of off-the-shelf parts, meaning those who get their hands on the hardware are free to upgrade everything inside — from the video card and processor right down to the motherboard. Also as a result of using freely available components, people will be free to build their own equivalent Steam Machine at home, save for the enclosure the prototype comes in — though even that will be possible to recreate, as Valve says it will be releasing the source CAD files for it.
