Lenovo's ThinkCentre 91z 7075D2G is a more suitable business PC than most all-in-ones we look at, with the exception of Apple's iMac range. However, it's also a perfectly viable home computer, and its business origins provide a number of features that set it apart from the majority of all-in-ones, most notably a massive three-year onsite warranty that'll have a repairman at your door within two business days of a fault being reported.
Like Apple, Lenovo has seen no need to use a touchscreen for the PC's 21.5in integrated display. This immediately cuts out the risk of a certain graininess that some touchscreens suffer. The display is glossy, though, and rather reflective if you're viewing a dark screen with a bright light behind you. However, colours are soft and natural-looking, although pure white tones aren't quite as bright as we've seen from our favourite monitors. Nonetheless, the 1,920x1,080 display is certainly up to the job. You can even use it as a standalone monitor, thanks to the VGA input at the back, and effortlessly switch between the input and PC at the press of a button on the front panel.
Inside, the PC has a 2.5GHz Intel Core i5-2400S processor - a power-efficient choice that we've seen in many of our favourite all-in-one PCs. It's doing a good job here, powering the 7075D2G to an overall score of 81 in our benchmark tests. The system comes with 4GB of memory; other versions of the PC come with more, and all incarnations are installed with a 64-bit version of Windows Professional.
The graphics processor is among the 7075D2G's weakest points - it relies on the Core i5's on-board GPU, which means that the best 3D gaming score we were able to get was 12.5fps in Dirt 3 at a resolution of 1,280x720 and High quality. You'll be able to run older games more smoothly, and casual gaming won't be a problem, but don't expect too much. The PC's other great problem is the capacity of its hard disk. At just 320GB, with 10GB occupied by the restore partition, we've not seen a PC with less disk space in quite some time.
