i know nothing about custom loops, well maybe a little (not much at all) i do know slightly about closed loops but i was wondering if anybody can explain "custom watercooling for dummies" maybe within the next 5 years or so i may be looking for these custom watercooling loops. as of today are there any cheaper kits for this that i could all fit in my case (which is a fractal design r4) the case has two 140 mm fan slots at the top, but the room between those slots and the motherboard isnt all that much, so i was wondering also if there are any options that have thin radiators, but also are 140mm x2. just something i may think about if and when the cash flow starts coming in XD. I definately wouldnt need custom watercooling at the moment considering i ahve a i5-3570k running at 4.4 ghz happily on air with a hyper 212 evo. but i enjoy learning about these things, and it may be a greater possibliity that i will use a custon watercooling loop later on
