When it launched back in June 2012, Alienware's original X51 system had all the merits of a Steam Machine without the title: It was small in stature and perfectly tuned for gaming in the livingroom. Packing Ivy Bridge, the three year old model had a marked advantage over the much smaller crowd of mini-ITX options on the market. And while gamers lauded the system for its compact design, any attempt to overclock the system usually resulted in complete system failure.Hot on the next iteration of Intel's processors, Alienware wasn't about to fall into the same pitfall again. And so, the firm has introduced a new line of X51 systems comes with a custom, miniaturized liquid-cooling solution, all starting at $1,099 (around £700, AU$1,500).Decide you need even more power than what the premium micro system can offer? A port for the proprietary Alienware Graphics Amplifier unlocks the system's 4K capability with help from a GeForce Titan X or GTX 960 GPUs.
