I plan on getting the airflow upgrade for the 750D If I do get it, none of my parts will be watercooled, and my only concern other than that is build quality, I've seen that the 750D can often have latches that break (e.g., the ones on the front panel)
CPU: i7 7700k
GPU: 1080 Ti
PSU: Corsair...
The aesthetics of this case just seem that much better than the pro 5, and the extra USB 3.0 ports would be useful to some people.
The fan controller used on the case is quite a nice addition.
As far as i'm concerned, it's a nice price compromise between the Pro 5 and the 5t, all the while...
