If you are looking to build a quiet setup, i wouldn't recommend going with H100i nor so many fans, unless you are overclocking heavy, in which case i would suggest go with custom waterloop and a case like Fractal Design Arc Midi R2
$$69 (atm on sale), it has offset rad mounts on the top, so the rad will end up facing more toward the side panel than the motherboard, allowing taller memory or wider rads, it also has imo better frontal rad support, i seen builds with 80mm think rads mounted on the front with very little modding.
Now if you intention is to build a quiet setup with R4, i would just go with Thermalright HR02 Macho
instead of the H100i, or really want something that is as capable in air, Thermalright Silver Arrow SBE
, i would click the black/white option and the extra fan to be placed on the back of the case and move the included fan to the front, to end up with 2 fans in and one out to have positive pressure.
