The 7075D2G's outstanding three-year warranty and serious processor power make it good value, but it has a small hard disk



2.5GHz Intel Core i5-2400S, 4GB RAM, 21.5in 1,920x1,080 display, Windows 7 Professional 64-bit

The remainder of the system's specification is rounded out with a memory card reader, DVD re-writer and six USB ports. There are no USB3 ports, which is a shame given the brand new Intel processor. We we were pleased to find that the system has an HDMI output, which makes it particularly easy to connect a second monitor, a projector or a larger display.

The integrated speakers, although lacking in bass, puts out a balanced and clear sound. There are also the obligatory 3.5mm headphone and mic ports for headset users. The mouse is a little small but we found it for extended use. The keyboard has a similar finish to its flat, widely spaced keys, which feel a bit spongy. It's also spill-proof, which should come as a relief to anyone who tends to eat at the computer.

Despite having a small hard disk, the ThinkCentre 91z 7075D2G is a good choice if you want a powerful and fairly versatile all-in-one PC. We still prefer the extra power you get - admittedly for more money - from the Asus ET2410INTS, but the 91z is worth buying if you want a decent processor but don't need much by way of graphical power or storage.
