Via The Seattle Times, here's your first look at Valve's Steam Machine prototype — a super-high-end machine that will be sent out to 300 beta testers later this year. (Those are Valve employees standing with it: from left to right, Eric Hope, Anna Sweet, Greg Coomer and D.J. Powers.)
If you're one of the lucky few beta testers, you'll get that massive piece of hardware alongside Valve's crazy controller for testing this fall.
As for the rest of us, well, The Seattle Times reports that we'll see a variety of different Steam Machines announced at CES in January, to be sold starting in mid-2014. We've already got at least some idea of what will be offered.
