I have a radeon r9 290x and I wanted to exchange the stock cooler with a cooler like the kraken x41 and g10. But unfortunately there is not enough room in my case, so I thought I could put the radiator, the fans and the pump outside of my case. But this is not possible with a closed loop system. So maybe a custom loop. But I am not really experienced in this kind of stuff. So I would like to have some kind of advice. How expensive it would a good custom loop get and does anybody have some recommendations for some kits? Or does anybody have some other good or better ideas what I should do?
