It is 190mm wide with apportion separated for cabling. 180mm of width for a cooler sounds right.The Tpc 812 is 163mm wide. The 212 X is158mm. They will likely make it. the 212x will a have alittle extra room. I would go with Hyper 212X.
On paper the 812 looks better. But In may reviews the 212 is right there with it. It is cheaper also.
