Hanover  - A nettop PC - a small, mini desktop computer - can function as an alternative to the classic desktop PC. These devices are compact and inexpensive, making them well suited for use as a simple workstation. They also consume relatively little power.

A nettop, like a netbook, is an inexpensive PC intended primarily for accessing the internet, explains Christof Windeck from the German computer magazine c't.

"That essentially means they're perfectly suited for using as a web browser, an e-mail client, and perhaps a simple photo editor for uploading images," says Windeck.

Designing these computers for light-duty work keeps them inexpensive and thrifty, yet also compact and quite reliable.

Nettops typically sell for around 300 dollars, says Michael Schmelzle from Germany's PC-Welt magazine. They tend to pack less processing power than standard PCs, but are much more energy efficient and quieter that their bigger cousins.

The hardware at work in these little machines also permits more compact case designs. That includes the "1-litre PC" category, with models like the Acer Aspire R3600 Revo and the Asus EEE Box.

Devices that come with Windows preinstalled typically feature a special version of Windows XP Home Edition. Vista comes with higher system requirements, making it ill suited for nettops.

One major plus for nettop PCs is their low power consumption. The Atom processor and graphic unit integrated into the chipset require between one tenth and one thirtieth of the energy of standard desktop processors.

A nettop requires approximately 30 to 40 watts, while a standard PC requires 100 to 120 watts, Schmelzle explains.

Because they are less powerful than modern PCs, nettop computers are best suited for simple tasks. These includes word processing, data backup, or internet surfing, explains Joerg Wissing, product manager at hardware maker Asus.

Those requiring more power for complicated office software, accounting, or 3D and graphics applications are better served with a classic desktop PC.

Passionate gamers and photo retouchers will also find the nettop experience frustrating. The devices groan under the strain of running 3D computer games or higher-end photo editing software. Nettops are also underpowered when it comes high-resolution internet videos.

"The playback is choppy and HD video off Blu-Rau discs usually doesn't work at all," says Wissing. Those determined to run 3D software on a nettop are advised to look for a unit with the Nvidia Ion chipset.

Nettops are ultimately attractive to users who want to surf the internet conveniently and affordably, as well as those looking for a computer that's not a power hog.

Looks play a role alongside the price, too, Wissing says. After all, the nettop can do more than just save energy. It looks good in the process. (dpa)
