My wife bought me an "InWin Dragonslayer matx" case to kickstart my gaming rig. I'm building around an intel core i5 2500k and possibly an Asus AP8H61-MLX mobo with 4GB G.Skill Ripjaws 1333 kit. I plan to overclock to 4Ghz. I'm not too sure about the stock heatsink so I wanna replace it with a CM Hyper 212. Will it fit in my case?
