Alienware has launched its X51 small form factor gaming PC, promising the gaming performance of a larger machine packed into a box small enough to fit into a living room entertainment set up.

"The Alienware X51 allows us to bring the exciting nature of high-definition, immersive gaming within reach of more gamers than ever before," said Arthur Lewis, vice-president, Alienware and Product Management for Consumer, Small and Medium Business. "With the X51, we've expanded our gaming desktop offering to cater to all gamers in addition to our core enthusiast and competitive gamers. Now everyone can enjoy the latest games on a sleek, powerful, compact and customisable system. The X51 desktop delivers an incredible feature set for its size and price."

The base level X51 is priced £699 and includes a Core i3 processor, 4GB memory, 1GB NVIDIA GeForce GT 545 graphics, and a 1TB 7,200rpm hard drive. Alienware states this specification yields an average 34 frames per second in Battlefield 3 at high settings and a resolution of 1080p.

You also get Wireless-N, HDMI 1.4 for connecting to 3D TVs, two USB 3.0 ports and High-Definition 7.1 audio.

The X51 has also been designed to be situated horizontally or vertically, giving more flexibility in confirmed spaces. In addition, the small form factor PC allows for user upgrades to hard drives, graphics and memory.

The unit measures 343mm x 95mm x 318mm and weighs 5.49 Kg.

At £699 the X51 certainly isn't cheap, and the hardware inside the base model isn't top end, but we can see a market for small form factor gaming and entertainment PCs for people who don't want a large box stood next to the TV.
