These cases will support a graphics card up to 315mm with a set of fans installed in the front of the case, so to figure out if your graphics card will fit with your radiator installed in the front, you will first need to find the thickness of the radiator.
Next, you will have to subtract the thickness of the radiator from the 315mm max length and that will give you your new max graphics card length.
Our Celsius S24 240mm radiator is 31mm thick.
315 - 31 = 284
So with the Celsius S24 installed in the front of these cases, you could install a graphics card up to 284mm long.
