Early this year, Dell introduced the Alienware X51, a miniature gaming PC just slightly larger than your average game console, yet still capable enough to play the latest games. Now, Alienware has some competition in that realm: the Digital Storm Bolt, a computer roughly the same size, but even more powerful. Despite having a chassis just 3.6 inches wide and 14 inches tall, Digital Storm's managed to cram a 500W power supply, a GeForce GTX 680 graphics card, and a Core i7-3770K CPU overclocked up to 4.6GHz.

Mind you, Digital Storm's a boutique retailer, and the Bolt isn't exactly a bang-for-the-buck machine. Compared to the Alienware X51, it's not nearly as cheap. Where the Alienware starts at $699, you'll have to shell out at least $999 for the base Bolt configuration, which comes with merely decent specs: a dual-core 3.1GHz Core i3-2100 processor, GeForce GT 650 graphics with 2GB of video memory, 8GB of memory, 1TB of storage, and an Asus H77 motherboard. Even at the $1,249 price point, which ups the ante to a Core i5-3570K CPU and GeForce GTX 660 graphics, the Alienware is a better deal... but that's about as powerful as the Alienware gets.
