After using this PC at work for over 3 months I can say it has been a joy! It has suffered no crashes running Vista business edition and has performed impeccably. I know that the Chinese bought out the IBM machines division and I was expecting a decrease in the overall quality but I have to say I was pleasantly surprised. The plastics feel good, don't appear brittle and haven't marked in 3 months. The keyboard is OK for a bundled effort but some of the letters seem misplaced on the actual key but other than that not bad.
The machine is exceptionally quiet, it is positioned at desk height and I cant even hear it, this compared to my Philips slimline at home sounds like a 747 at take off speed!!
Overall a well specified well built machine with all the features expected in this price range, I will be purchasing more when other machines need updating rather than defaulting to DELL.
