juanrdp :
You have any reason to go for a water cooling solution instead on a good Air solution or it's just because "it's better water cooling"?
True what juanrdp, you got a max of 170mm height for a cooler which is enought for a good air cooler. I was forced due to max 140mm height to go watercooling but you got plenty of space.
EDIT: To be on topic, yes CM neptun or deepcool maelstrom 120 is good too, also corsair h80i is a good choice and with this cooler if u get a better fan for this radiators u can get even better performances, i plan to geta delta fan of 5000 rpm.
