Having checked out a sample of the prices on the weblink above I can't see any savings from shrewd buying in the UK. Check out websites like ebuyer and novatech for the various components to make your super duper all singing all dancing pc. You can buy carcasses as well complete with case, psu, mobo, processor and RAM and use that as a base to add on all the bells and whistles you require. Just check out ebay for deals on those, far to many to mention. I really wouldn't bother with the hassle of buying overseas and then trying to pack it into my bags.
