I have a Rosewill Challenger case and will be dropping it into this mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813128659 which will all be going into a Rosewill Challenger ATX mid tower case. I am looking to do a bit of overclocking, nothing too heinous yet, and I know I will need an aftermarket heat sink. Currently looking at a CM Hyper 212 EVO, buit I want to pick the community's brains first. What do you think guys?
