Front
Up to 240/280 mm
If mounted a radiator longer than 285 mm, you would need to have a push configuration, as the radiator would otherwise interfere with the top I/O plastic cover. The fans need to be at least 21 mm thick. You would then have a maximum radiator thickness of 52 mm. If the fans are thicker than 21 mm, you reduce the additional millimeters from the 52 mm mentioned for maximum radiator thickness. For example, with 25 mm thick fans, which are 4 mm longer, the maximum radiator thickness is (52 - 4) 48 mm.
