Good review ... marfig's questions/thoughts caused to reread a couple of times. I see this case as the ultimate WC kit; good for a serious 1st WC experience. Meaning it has all of the necessary parts w/o the effort to have to figure out this versus that component. That can be both tedious and interesting .. and fun.
As far as air flowing into the case versus out, there seems to be ample air flow thru the case for exhaust. But I have not looked at the fan capacities or noise levels .. oh, wait, that is not available with a kit? (I apologize if it is as I did not read in enough detail as yet.) I imagine replacing the fans on the radiators with my latest preference. The rest, unless noisy, would be fine. The case for air flowing into the case thru the radiators puts the coolest air thru those radiators. Never the less, in my push pull fan configuration with my radiators, they blow out.
About power supplies at the bottom or top with respect to heat, I don't see this as an issue. PSUs are so efficient that I don't expect much heat from the PSU. Even then, it has it's own fan to remove heat right at the source. Cable management is another thing & I agree with Greg & maybe this is the best point about the case (from my point of view).
That is the option of mounting the PSU in the top or bottom (did I read this right?). I have cases that are one or the other & there is always some thing too short or too long or not needed (but I only buy Seasonic X750 PSUs which are modular & usually never a heat issue).
In summary, I am in the market for new cases & I like this case. It is high on my definite maybe list.
