ADDITIONAL COMMENTS:
-Quiet PC is nice
-I don't like/care for glow lights on the case that are irritating
-Not fussed about OS - if you could suggest 32/64 bit i would be greatful.
Unfortunately, I'm not too familiar with the site you mentioned, but I can suggest that you get 32-bit Windows, to maximize compatibility. There are many games and apps that don't work with 64-bit Windows.
