If money doesn't matter(Both cases are within/above 150$ mark), I'd prefer the 760t of the HAFx. I like corsair's case better due to that huge acrylic side panel and with appropriate cable sleeving, colour coordinating, and led lighting, can make a build look outstanding. Not to mention that you can remove the drive cages to have unrestricted intake airflow(Just buy a 3.5 → 5.25 bay adapter for HDD's).

But then again the HAF series from CM is more oriented for internal airflow, hence the name: HIgh Air Flow(IDK if it's true, i just thought it made sense). Cooler Master includes a 200mm fan for intake and gives you an additional fan mount on the side panel so your GPU can get even more fresh air from outside the case.

As for CLC's please don't get the H100i, it's very loud. I'd recommend the Kraken x61 or Swiftech 240X(Why? idk. paging vagabond139).

• ^{Formatting will be (X case fan vs Corsair)} Corsair fans are not terribly good(Their AF series is aight), especially their "Static-pressure fans". Low af CFM, mediocre static pressure. Something like the CM Sickle Flow would be better. Higher Airflow(69 cfm vs 37.9 cfm), Lower DB(19 vs 23), Higher Static pressure(2.94mm/H2O vs 1.29mm/H2O) with 120mm models. As for the corsair airflow line, it is(aight, but) outperformed by a few other fans such as the AeroCool DS 140mm(also comes in red led, blue led, and white led). For the same reasons(I'll be using 7V for areocool's fans): Airflow(71.2CFM vs 67.8CFM), Noise(15.5DBa vs 24DBa), and static pressure is negligible due to both being airflow centralized fans, but i'll provide it anyway(1.41mm/H2O vs 0.84mm/H2O).

All in all(Back to the case recommendation) I'd choose the 760t over the HAFx, but it all depends on your personal preference in aesthetics between the two cases. Both are in the same price range(150$ - 200$).
