Graphics card specifications vary by add-in-card manufacturer. Please refer to the following guidelines when picking your GPU.

Max supported GPU dimension, 310mm x 149mm. Note that if you are installing a waterblock, they often have protruding fitting mounts that adds to the height/length.


Up to 4-slot GPU is supported. Please note that the rear IO Panel only has 2 slot openings. This is not a problem for 3-slot cards like the GeForce RTX™ Founders Edition as the 3rd slot has no ports. Only 3-slots supported for Classic and Reverse mode.



Max height 140mm when side radiator not used.

Fan Mount

120mm or 140mm fans can be mounted on the base or top panels.


240mm radiators can be mounted on the base or top panels in positions same as fans. In addition, radiators can also be side mounted by resting on the PSU panel.

Radiator thickness 

When used together with fans, total radiator thickness must be carefully considered. Side mounted radiator allows for the biggest flexibility with standard thickness fans and radiator.

For other positions, consider using slim fans and radiators.

PSU Mount

The PSU mount is a multipurpose panel and can be used for mounting SSD drives or pump.
