This watercooling kit is getting sold on ebay for only 59.99 pounds excluding shipping http://tinyurl.com/Magicool108 This is an incredible price, is it good for watercooling or is it later on going to be a problem?
You would only be able to cool the CPU (thin 120mm rad) so you may as well go for one of the corsair AIO units (h50/60). It would give same cooling for a lot less hassle
I like open watercooling that has access to the coolant including viewing so Corsair closed is not good.
You'll probably get better performance and support from one of the Corsair units too. FYI there is no 'budget' watercooling, only expensive and less expensive
But the fan Inc. Will be awful and the pump will be loud. I don't know this but for £60 its very probable
