The aggressively styled red-and-black Spark measures just 4.5 x 4.2 x 2.3 inches, so it won't take up too much room on your entertainment stand. And it weighs in at just 0.98 pounds, according to Maingear. Its tiny size is due to its mostly laptop-class internals. But with a quad-core AMD A8 processor that tops out at 3.1GHz, brand-new AMD R9 M275X graphics, and up to 16GB of RAM, it should have enough power to make modern games look pretty good on your HDTV. There's also room inside for two drives: an SSD to run games from for fast load times, and a hard drive to store media files. Four USB 3.0 ports let you add extra storage or other devices.
