Update, threw a CoolerMaster Seidon 120V in, it fits fine with the 120mm included fan.
So... 140mm fan hits the RAM sticks, should be able to use the 120mm fan though. OR, you can buy/install 120mm radiator, works fine!
Max CPU temps dropped 10°C, so airflow obviously is better!
tl;dr - use a 120mm liquid CPU cooler in the Elite 110 case.
