The prototype versions of the Steam Box, codenamed Piston, Valve’s answer to console gaming should be ready for testing in about a month. From what i understand  some minor issues are trying to be addressed before hand. Typical noise and overheating problems along with a finalization for the controller layout. It is understood that Valve will send the prototypes out to gamers of their choosing, so i guess begging to get your hands on one will not work.

The demo unit of Piston featured at CES has the following features: ethernet port, 4 USB 3.0 ports, 4 USB 2.0 ports, 4 eSATAp ports, 2 Mini Display Ports and 1 DisplayPort/HDMI port and much more.
