Make your own kit: - Radiator with 2 or 3 12cm fans - Pump - Hoses and clips - Liquid, not just plain water - Resevoir - And the cooling blocks; CPU, GPU and chipset for example The pump is for me always the most important part; it must be the most reliable part of your system. Some external radiators have build in pumps; look at the Zalman for example. I see also that the site you gave me doesn’t offer so much, well, they have pictures but nothing in stock . You are going to pay fleet-cost any way so why don’t you get it outside the UK? Just make sure the pump is 115volts and there you go . And remember that you have to drill and kut in your case most of the time!
