Straight up, you want AIOs just avoid the case completely. dont even read further.
technically you should have your fans directly on your rad. With this case design Full 360 rads will fit in top panel and front (on the inner structure) and fans should go on the outside (between the glass and the inner structure. I imagine this isnt good for performance. Remove the air dust filters and i think it should be just the same. but your fan potential are hindered by the glass
Both fans and rads on the inner side wouldnt work (top panel) at all (any and all sizes)
You could get away with 240- 280 rad and fans in the FRONT and you will have to remove the air guide.
Also you could do the 360 and fans on the inner but you would have to remove the power cover and the air guide.
As for balancing air. Never considered it until now. I have an I5 9600kf , A400 antec air cooler and a Gtx 1060 the heat is alot but system chills around 40-45 degrees Celsius. So heat manages well. My suggestion for a AIO set up.
ideally i would want best performance that would be a dual rad on the front panel, however the distance for the pipe would need to be at least 33-35 cm to comfortably reach. i dont know AIO pipe lengths.
So you would have 360 rad top, remove dust filter top and your only option is to put if make the first 1 extake the other 2 intake, front panel 3 intake, plus exhaust. Lol sounds so stupid. I realised now im not getting an AIO . Hahahah ! wow
