Love the look of the build. 2 possible, minor tweaks. Have you tried reversing the flow? Leave everything where it is, but reverse the fan directions so you are pulling cool air into the case, through the radiator, and then out the top - while I get you want to keep the mobo/RAM cool, it is almost always better to feed to coolest air into your radiator to cool the major components. Also, is the riser cable flexible enough to route behind the case? Would look much cleaner if you dropped it to the back of the case (where the rest of the wiring is hidden) and then had it pop out at the GPU.
