I recently bought a laptop from PC Specialist and am very happy with it. Good price and customer reviews. Easy to select the base model and then customise components to suit your requirements and budget. It will take between 7 and 14 days to build and test.

I was also looking at a desktop from Chillblast. Good value and some great reviews in PC magazines. Also customisable components, so easy to get the specifications to suit your needs, and more for the gamer.
