Alienware has successfully brought its brand to an affordable, suitably stylized package, and I can recommend the X51 to anyone in the market for a mainstream gaming PC.
Its gaming performance is impressive for both its size and its price, and the case’s lighting scheme and sleek lines give it a style that’s intimidating without going over the top.
In that regard, gaming performance of the X51 was, for all intents and purposes, the fastest of the bunch among the other full-sized systems we tested.
Nice performance from a compact system. Easy-to-service interior. USB 3.0 ports. HDMI video output. Up to three monitor support. Integrated Wi-Fi.
