Meet Alienware's Alpha console, a Steam Machine without SteamOS (for now)
That's not to say the Alienware Alpha will launch without Steam, however. While the first-generation Alienware Alpha will ship with Windows 8.1 preinstalled, it'll also feature a customized, living room-ready "console mode" interface built to let you open Steam Big Picture, media, and other programs using a gamepad alone. Valve helped Alienware tweak the Alpha's Steam Big Picture installation to include graphical elements that tie into the console's glowing lights and overall design aesthetic, according to Alienware general manager Frank Azor.
"Steam Big Picture mode is a great solution already," says Azor. "It's been shipping for over a year, so it's a mature solution."
You can install any PC program on the Alpha, though third-party programs may require a mouse or keyboard to function properly, or even boot to the traditional Windows 8.1 interface if you'd prefer. When Valve does finally make SteamOS available, early buyers will be able to switch to that operating system without fear of voiding their warranty, though it won't be required.
Under the hood
Unlike some of the fire-breathing Steam Machines announced to date, the Alienware Alpha largely mimics traditional consoles, from its $550 price point to its small footprint to its bundled gamepad. The latter is an Xbox 360 controller in lieu of the delayed Steam Controller, though Azor says the Alpha also supports the PlayStation 3 controller, and others that Alienware's peripheral partners will announce in due time. Alienware's also considering releasing an Alpha variant that ships without a gamepad, to bring the console's cost down even more.
