Best gaming desktops, big and small

Alienware X51

CNET rating: 4 stars out of 5 (Excellent)

The good: The affordable Alienware X51 brings innovation to slim-tower PCs by offering a full-size graphics card.

The bad: Despite the big 3D card, the X51's slim-tower chassis still has a limited upgrade path.

The cost: $999

The bottom line: 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.
