recommend good air cpu coolers or water cpu coolers other than cooler master hyper 212 evo which can be easily fitted in cooler master haf 912 combat transparent case.
I have one of those Corsair H60i AIO water cooling solutions,and while its not bad..its certainly not the best..i would still recommend getting a decent air cooler over one of these AIO kits.
Like said, would need to know what processor and if your going to overclock. If not overclocking getting anything other then what you all already have would be a waste of money.
