Lenovo has begun shipping its ultra-slim IdeaCentre A300 all-in-one desktop computer to the US. Claiming to be the world's thinnest AIO, the A300's 21.5-inch 1080p LED display measures only 18.5mm thick, and the complete dimensions are 524 x 396 x 207mm (20.6 x 15.5 x 8.14 inches). As you can probably tell by the picture, the panel's trim profile is accomplished by using machine's inner-workings as a base instead of stashing them behind the screen.

The IdeaCentre A300 is available a few configurations, all of which are Intel-based. A $799 setup gets you a 2.20GHz Pentium Dual Core T4400, GMA X4500 graphics, 2GB of DDR3 1066MHz RAM, and a 320GB hard drive. The remaining models cost $949 to $999 and have a 2.20GHz Core 2 Duo T6600, 4GB of RAM, 500GB of storage, and a TV tuner. Along with a built-in webcam, the system ships with a Bluetooth wireless keyboard and mouse, HDMI-output, an 8-in-1 card reader, and Windows 7 Home Premium x64.
