Alienware plans to launch its Steam Machine in September, the company announced at Valve's Steam Dev Days developer summit on Wednesday. Alienware, which is owned by Dell, is one of the first companies to partner with Valve to create a SteamOS game.

Alienware is still being quiet about specifics, including price and internal specification, but says its X51 Steam Machine will offer "a sleek design which is both distinctively Alienware yet unobtrusive in a media cabinet". It's 8-inches long and 3-inches high, and will have an Intel CPU for power and Nvidia GPU for 1080p graphics.

The custom-built chassis will provide optimal thermal and acoustic management, says Alienware. Hopefully it will be quiet and cool enough to sit comfortably behind a screen or hidden in a closed cabinet without distracting gamers from the big-screen experience.

Essentially, Alienware is going after the next-generation Xbox One and PlayStation 4 consoles with its hardware. Alienware will also ship Valve's Steam Controller with its gaming PC come September.

Alienware was among the 11 other partners featured as Valve's official Steam Machines partners at CES 2014. Other companies included Falcon Northwest, iBuyPower, CyberPowerPC, Origin PC, Gigabyte,, Webhallen, Alternate, Next, Zotac and Scan Computers.
