The rear supports a 120 mm radiator.
The top panel supports 120/240/360 radiators, with a max radiator length of 407 mm.
Note that the max radiator width is 121 mm, and the maximum motherboard component height (mainly affects RAM, so check your RAM-height) is 47 mm.
140/280/420 radiators are not compatible in the top. The top neither has the holes nor the width for this form factor.
There is no radiator support in the front.
