The Valve Steam Box, now revealed to be not one, but a series of licensed Steam Machines, has been one of the most hotly anticipated developments in gaming in the past year. They're gaming PCs, built by a number of manufacturers, that run Valve’s SteamOS and works with the company’s upcoming Steam Controller. Valve gave us a sneak peek at what Steam Machines will look like at a press event here at CES.

Valve brought together more than a dozen hardware partners to show off their potential Steam Machines. They range from the compact (sleek set-top-box form factors) to the monstrous (big and boxy) the inexpensive (low hundreds) to the pricey (mid thousands), and the modest to the supremely powerful. Steam Machines look like they will be as varied as gaming PCs themselves, and are built by many of the same companies. Since it's still early in the game, many of them don't even have model names yet. (When you see "Steam Machine" in the slide titles, the model name is TBD.)

On the high end, Digital Storm showed the Bolt II, and Falcon Northwest displayed the Tiki. The Bolt II has an expected price of $2,584, while the Tiki will run from $1,799 to $6,000 depending on configuration. They pack the hardware of high-end gaming PCs, with an Intel Core i7 CPU confirmed for the Bolt II and an Nvidia GeForce GTX Titan GPU in the Tiki.

For more modest boxes, iBuyPower, CyberPower, and Zotac had Steam Machines with list prices ranging from $499 to $599, with Intel Core i5 or AMD CPUs and less-beefy graphics cards.

Alienware boasted the most mysterious box. The company would not release any information about the system’s specs. However, it has a striking, angular design with glowing Alienware and Steam logos that can change colors. It's one of the better looking Steam machines we've seen.
