Install up to four storage drives via two 2.5/3.5" drive bays and two 2.5" drive mounts. GPUs up to 15.55", CPU coolers up to 6.69", and SFX and SFX-L power supplies up to 6.49" are supported. Keep components cool with support for up to nine 120mm fans or seven 140mm fans. Radiators up to 360mm can be installed at the top and bottom of the case, while the side panel can accept radiators up to 280mm. Magnetic dust filters and dust trays at the top, bottom, and side keep your rig looking clean. Along with a steel frame, the O11 Dynamic Mini sports an aluminum exterior and tempered glass side panel for showing off internals.
