Enthoo Lux + EK CE 420 = It fits
For those that were wondering. With my Asus IX Maximus Hero it only fits with the ports facing the front. You'll have to remove the top and drill a few holes to gain access to a couple fan mount holes. You'll see when you start fitting.
Also, There's plenty of room between the mobo and radiator.
