The Steam box is a reality,will come in multiple forms on release

Steam Machines-ss01 The second countdown has ended and Valve has announced the highly rumored Steam Box with the name "Steam Machines". This system will come in multiple forms from different manufacturers, all using the Linux-based SteamOS. They have a prototype, and Valve wants to send the prototype to 300 Steam users for testing purposes. Check out if your eligible. 

It's pretty easy to be on that eligible list, but your pretty much going against millions of users that want to be within the lucky 300. But trying won't hurt, here are the steps:

Before October 25, log in to Steam and then visit your quest page to track your current status towards beta test eligibility

1. Join the Steam Universe community group 2. Agree to the Steam Hardware Beta Terms and Conditions 3. Make 10 Steam friends (if you haven't already) 4. Create a public Steam Community profile (if you haven't already) 5. Play a game using a gamepad in Big Picture mode

Valve didn't talk about specs or anything but they did mention in the reveal that these "Steam Machines" are completely upgradable and open.

There's still one more announcement left for Valve's three-part reveal and my guess is either a new source engine, a game exclusive to this box, or the box's controller.
