Valve has announced that its made-for-gaming Linux-based Steam OS will be available to download on 13 December.
It recommends that only "intrepid Linux hackers" download Steam OS for the time being, until it's more polished next year, but we're sure that won't stop PC gamers with itchy feet from jumping in as soon as possible.
Valve also announced that it will be shipping Steam Machines and controllers to 300 lucky beta participants on the 13th too, but only to US gamers. Boo, hiss.

There's a storm brewing
In other related news, Digital Storm has revealed a US$1,470 (S$1846) gaming PC which can dual-boot Windows and Steam OS.
It's packed with a dual-worthy Nvidia GTX Titan graphics card and liquid cooling, and we can't wait to see it in the flesh at CES in January.
