The Alienware Steam machine is powered by an Intel Core i5 4570, an NVIDIA GTX 760 GPU, 16GBs of RAM and up to 1TB of storage, using a hybrid hard drive and solid state drive (SSD). This boxy device will sell for $1,339 and be available in mid-2014.
Dell's Alienware will be using Valve's new gaming controller, but other vendors will be using different designs. No matter the controller, you should be able to any of them with any other Steam Machine.
