Asus is adding two high-definition models to its Eee Box line-up. The Asus Eee Box B204 and B206 have just gone onsale in the US and boast HDMI connectors and pre-N Wi-Fi for wireless streaming.

Both new Eee boxes are fitted with 256MB ATI Radeon HD 3400 graphics cards, enabling users to watch high-definition video content.

Asus' press release says "users will be able to enjoy viewing hardware-accelerated HD content on LCD TVs, monitors and projectors via an HDMI output".

To ensure a smooth video viewing experience, there is an Asus Cinema application that functions as an onboard media management console and offers compatibility with a large range of video formats. A remote control is also supplied with the Asus Eee Box B204 and B206, which are small enough to fit behind a flatpanel display and be hidden from sight.

Asus says the Eee Box range is the world's smallest. The unobtrusive white units are similar in size to a paperback book. They can even be VESA-mounted to the back of a screen and need never be seen. If this is done, the effect should be much like an Apple iMac or an all-in-one PC that has the computer components built in to the flatpanel display.

Asus is keen to stress the low energy consumption of the Eee Box: it requires only 20 Watts of power, compared to as much as 200W to 300W for a standard desktop computer.

Both the Eee Box B204 and B206 run Windows XP Home, 1GB of RAM, a 1.6GHz Intel Atom N270 processor and 160GB hard disk. In addition, owners get 10GB of secure online storage as part of the package. The Eee Boxes offer 802.11 b, g and n Wi-Fi, Bluetooth and a multi-format media card reader.

The B204 model will also have a built-in UPS (uninterruptible power supply) so data is not lost should the power supply fail - a not uncommon occurrence in some parts of the US, where the devices are initially launching.

No word on a UK launch of the Asus Eee Box has yet been confirmed. However, Digitimes is reporting that there will soon be a new 120GB model of Eee Box priced £160.
