it will fit, the cm 212+ is 6.2" tall while the case is 7.8" wide.
Thanks for the reply dirtyferret. I saw the specs on each of these previous to this post. With a case 7.8" wide and the heatsink being 6.2", that only leaves 1.6" of interior space (maybe). My concern is how much room does the motherboard tray, and motherboard itself, take out of the 1.6" remaining. Opening the case and taking very crude measurements, it looks like I have about 6" exactly. I could take everything out and measure precisely, but I am hoping there is someone here with the same case?
And thanks for the recommendation on the other heatsink Ablekl, it does look better!
