Front
Up to 360x120 mm / 280x140 mm
Radiators longer than 380 mm will need to run in push-configuration with a minimum of 24 mm thick fans, as it would otherwise interfere with the top I/O-plastic. The radiators can then be up to 403 mm long.
When mounting a radiator longer than 380 mm, you have, in combination with standard 25 mm thick fans, a maximum radiator thickness of 44 mm. If you have even thicker fans, reduce the extra thickness from the maximum radiator thickness. For example, 27 mm fans, which differs 2 mm, would give you a maximum radiator thickness of 42 mm.
Measurements for front:
380 mm from bottom bracket to top I/O plastic cover
45 mm from I/O plastic cover to refill port(distance for radiator to fit within when longer than 380 mm)
403 mm from bottom bracket to top panel
Bottom
Up to 240x120 mm/ 280x140 mm
If you mount a 280 or 140 mm radiator,the maximum width is 140 mm. If you mount a 240/120 mm radiator, the maximum width is 120 mm.
Measurements for bottom:
330 mm from rear PCIE slots to front fan
368 mm from rear PCIE slots to front fan bracket(when 38 mm thick fans are removed)
When radiator is mounted directly to the bottom bracket, the distance from the center of the mounting slot to the closest interference(plastic clip for bottom cover) is 7.5 mm
When fans are mounted directly to the bottom bracket with the radiator above it, the distance from the center of the mounting slot to the closest interference(metal bracket for TG-panel) is 16 mm.
