How to use

For right-side radiator installation, remove the detachable fan bracket and place either three 120/140 mm fans or a 360/420 mm AIO radiator. The three 3 mm tempered glass panels and side perforated panels are removable without tools to ease component installation and cable routing.

Recommendations

When using an AIO radiator, position the radiator higher than the pump to improve coolant flow and reduce the risk of air trapping. Use the optional Chassis Stand Kit for horizontal placement if you want an alternate viewing orientation, and consider the 3.9" LCD Screen Kit (sold separately) to display system information and custom images.
