VeryPC GreenPC TT3V

And, as usual with VeryPC, the base unit we've reviewed can be customised with all manner of upgrades and extras. The CPU can be boosted to a quad-core model for between £63 and £174 exc VAT; the 2GB of RAM can be doubled for £18; and a 7,200rpm, 500GB hard disk costs £55.

A Blu-ray upgrade is also available at £176, but with HDMI outputs appearing only on the forthcoming consumer version of this machine, this seems somewhat unnecessary. We've also been assured that wireless and TV tuner options will be available for use in the PCI Express 1x slot, although no pricing details are available as yet.

But while the TT3V may be a frugal PC in a stylish chassis, its lack of business-focused features mean that it falls behind our current favourite corporate PC - the Lenovo ThinkCentre M58.

While the VeryPC is faster in our benchmarks, the Lenovo includes double the amount of storage, basic peripherals, and a more versatile chassis for about the same price. Consequently, the TT3V may be the best Treeton yet, but it's worth buying only if a low power draw is your main concern.
