Officially, the unofficial Steam Box known as the Xi3 Piston will be available for preorder immediately with the launch event coming in time for the 2013 holiday season according to Xi3 Corporation, makers of the Steam Box. Pricey would be a good description for the Xi3 Piston, with prices starting at $1000 up to $1750 according to hardware configuration.
This hardware will without a doubt go under like Ouya and the Oculus Rift, good luck with all of this shit especially with Razer's Edge and Nvidia's Project Shield in the market Plus stupid ass gaming Consoles have fun with it all because I'll be playing Triple AAA Game's using two GeForce GTX 670 in SLI "Losers".
