I see your concern about heat from the CPU cooler.
Suggest you check the orientation of your CPU cooler.
If possible, install the cooler with its fins pointing to that long strip of vents so that roughly half of the exhaust will go in that direction and escapes the case. This is better than having the fins running parallel to the strip of vents.
See the 2 pics below for illustration. Pic #1 is not ideal while pic 2 shows a better orientation.
Got it, thanks a lot for the help . It seems to be already in that orientation. Sorry for going off track.
I'm not entirely sure if this has been mentioned before, but there's pre-orders on two new Mac Pro inspired cases. One is a M1 layout with 240mm aio support with the included bracket, The other is in Cerberus layout with M-ATX motherboard support.
