While some of the most powerful gaming systems still reside inside gargantuan full tower enclosures, a growing number of decked out desktops have gone the opposite route. One of the best examples of this is Origin PC's Chronos line of small form factor gaming PCs. With a footprint measuring a scant 4 inches wide and less than 14 inches deep, the Chronos is about the size of a dedicated game console, but is packed chock full of bleeding edge hardware capable of big time gaming performance.
