Upgrading the Dell Studio XPS for Gaming

The Dell Studio XPS (model MT435) contains the new Intel Core i7 processor, but this range of machines is not designed to compete with their profitable gaming line (for which any i7 model is hugely expensive at present). The XPS model comes in a smaller case with a mATX size main board.

On the back of the machine, note the 92mm case fan and the 80mm rear venting PSU.
