Front radiator
For front radiators, there is no direct restriction for anything between 120 mm and 360 mm radiators except that you should make sure the GPU length allows for installation.
For 420 mm radiators, there are however a few restrictions:
The maximum radiator length is 465 mm.
The maximum radiator thickness is 40 mm (will otherwise interfere with top part of case).
Requires mounting with tubes facing up and not down.
The distance between the top radiator screw to the end of the radiator on the tube-side needs to be a maximum of 35 mm.
The other end with no tubes need a maximum of 30 mm between the edge of the radiator to the screw hole.
Top radiator:
For 280 mm radiators, the maximum width is 157 mm. For 360 mm radiators, the maximum width is 137 mm.
Rear radiator
You can only fit a 120 mm radiator in the rear.
