I'd have to agree, I went with the enthoo pro and really enjoy it. Especially for the price. No case is flawless, if someone wanted to nitpick things they could find something they wished was different. It's roomy, good cable management, lots of included extras (various screws, thumb screws etc). I'm also not personally a fan of aio coolers. The dual radiators (240mm with dual fans) like the h100i are the smallest I'd consider unless it was special circumstance like a tiny case, mini itx or something where a traditional cooler or larger aio wouldn't fit. May as well pass on the single aio's like the h60/80.
Aio's like the h100i tend to be noisy or louder than a good air cooler anyway. If I had to go aio I'd probably consider something like kraken x61 which is a 280mm radiator. Even then you're looking at around only 4-5c temp improvement over an nh-d14 air cooler and the nh-d14 is quieter by a decibel and costs $75 instead of $115.
Here's a review on the kraken x61

Given how large the enthoo pro is in width it will handle large air coolers like the thermalright true spirit 140 power which can meet or slightly exceed cooling performance of the nh-d14 at similar sound levels for $50.

An nh-d14/d-15 you may have to consider shorter ram or adjust your lead cooling fan up a bit to make room. Unless it's purely for looks or to be able to say it's water cooled, large air coolers are more than sufficient to cool the 4790k even at max overclock. There are a number of larger air coolers to choose from, whether the nh-d14, nh-d15, true spirit 140 power, be quiet dark rock pro 3, phanteks tc14pe, cryorig r1 etc. For strictly cpu cooling especially intel cpu's, they run cool enough anymore and air coolers have advanced enough that water cooling (aio or custom loop) are novelty. You'll hit voltage limits before you reach thermal limits of larger air coolers.
Custom loops do have a place if it's whole system cooling, cpu, gpu(s) etc tied together and a well thought out loop with multiple large radiators can handle highly overclocked systems quietly. That's much different from aio's and can easily get into several hundred dollars though too.
If going for looks, there's also the raijintek triton. Cools just slightly better and just slightly better noise than the h110. Has a clear cube mini reservoir on top of the water block with blue, red or green coolant in it and uses a couple of led's to light it up.
This is the blue one, but newegg carries all 3 colors and they're all the same price.
