Lenovo has launched the IdeaCentre A300 - an all-in-one PC, which the company claims is the world's thinnest.

The 18.5mm all-in-one PC features a 21.5in 1920x1080 resolution widescreen display, putting the final dimensions at 524x396x207mm.

It also has a rather striking design, setting it apart from its older (and thicker) sibling, the Lenovo IdeaCentre A600.

Despite the meagre footprint Lenovo managed to pack in quite a few features, including a Core 2 Duo processor, 4GB of DDR3-1066 MHz RAM, and up to 500 GB of hard drive space.

Intel X4500HD integrated graphics will drive the display, so don't expect to do much gaming.

Connectivity options include four USB ports, a multi-format card reader, a FireWire port and HDMI in and out ports. You'll also find a webcam, integrated 802.11n Wi-Fi and a wireless Bluetooth keyboard and mouse, for minimal cable clutter.

The Lenovo IdeaCentre A300 all-in-one will be available in the US in February, starting at $600 (about £375) - but expect to pay a bit more for the roomier hard drive, faster processor and optional extras such as the integrated TV tuner or an external optical drive. UK pricing has not yet been revealed.

While it certainly looks great, we'll have to wait to see how it stacks up against other all-in-one PCs.
