I managed to fit a 212X into my Corsair 100R Silent case. Theeennn I went all out and managed to fit this massive Noctua NH-D14 into it. I have customised the case by removing the drive bays, swapping to a windowed side and making the front vented. Kept the large center fan, but couldn't use the front fan. So I doubled up on 2x 120mm exhaust fans. It's all very very tight. The side of the window, juuust touches the top of the cooler. My setup won't win any looks contests but it's exactly what I want due to where I have my case, hence why I needed to keep it all in a midi case.
Edit: The D14 is 160mm in height. The newer D15 is 5mm taller in height due to where the center fan sits, if I remember correctly. Which means the D15 won't fit with any fans mounted.
