Custom-built computer vendor Digital Storm has announced what it claims is the world's thinnest gaming machine. Measuring just 3.6 inches thick and 14 inches tall, the Bolt PC packs a good amount of punch inside its svelte chassis, including an Intel Core i7 3770K processor, a 120GB SSD plus 1TB HDD storage, an Nvidia GeForce GTX 680 2GB graphics card, and 16GB of RAM on the range-topping $1,949 configuration.

The Bolt is just slightly thinner and taller than Alienware's X51 small form factor gaming rig, unveiled earlier this year. Its Mini-ITX chassis is said to be specially designed for heat dissipation and space efficiency, while still offering the flexibility of manual upgrades using full sized components.

The base configuration starts at $999 and comes with 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. For $1,249 Digital Storms ups the specs to a Core i5-3570K CPU and GeForce GTX 660 graphics, while $1,599 gets you a 60GB SSD alongside that 1TB hard drive and a Gigabyte Z77 motherboard.

All four models come with a DVD recordable drive, 500W power supply and Windows 7 Home Premium.

In terms of pricing, Alienware's X51 offers a better deal than the two lower end models, but if you are looking for a gaming rig in a small package the Bolt PC offers more powerful configurations.
