I have a friend who's looking to upgrade his computer, was wondering if anyone could point me to some good custom built computer sites or good sites to buy parts that ship to Europe? I unfortunately only know of American sites, clueless to where European buy their hardware.
Tell him to google it. In Denmark the have a site called http://edbpriser.dk/forsiden.asp
and I think it is as well in Sweden they are a price guide with links to all the vendors in their respective countries arranged by lowest to highest price for every given piece of hardware.
