Alienware, the American computer hardware outfit owned by Dell Inc., has announced that its first Steam Machine will be available for the public to get its hands on in November. The Alienware Alpha looks likely to be the first commercially available Steam Machine when it launches, but rather than being built on top of Valve's SteamOS, the Alpha hardware will be reliant on Microsoft's Windows 8.1 operating system. The curiosities doesn’t stop there either as Alienware looks to penetrate the PC gaming market with a Steam Machine that is likely to differ vastly from the initial crop that hit the market.
