Unfortunately not, unless you "edit" the inside clearance of the case, so I'm now building my own Custome case 😅😂 But it could also be that you can order the template for 420mm mounting from nzxt.
According to geizhals information, 3*140 fans fit in the front. But radiator size only up to 360
I could well imagine that the radiator could be mounted on the fans, but there may be a blockage in the interior.
Maybe ask the manufacturer directly because I find it contradictory that 3*140 fans fit but an AIO with the size of 420 with the radiator then not according to the specifications.
(But there are better cases for the money the nzxt costs. Maybe better take another one which is more designed for custon wakü ! )..
Greetings go out 😎👋 and have fun tinkering when you have found the right one.
