Velztorm O11D Mini Red PC Case

Compact ATX Mini Tower

The Velztorm O11D Mini Red is an aluminium and tempered-glass chassis that accepts Mini-ITX, Micro-ATX and ATX motherboards. Its dual-chamber layout separates the power supply and drives from the main components for cleaner cable routing. Three magnetic dust filters and a removable tray protect the interior from debris. Builders who want a larger E-ATX board or more than seven expansion slots should look elsewhere.

Motherboard and PSU fit

Verify that your board matches one of the three supported form factors before ordering. The power supply must be SFX or SFX-L; standard ATX units will not mount. Choose between the supplied back-panel options for three vertical or five to seven horizontal expansion slots depending on your GPU and add-in card count. Radiator length at the top is limited to 360 mm, 280 mm or 240 mm.

Sustained thermal behaviour

A 30 mm gap behind the side bracket lets fresh air reach a radiator directly while still clearing long graphics cards. Top mounts accept three 120 mm or two 140 mm fans, side mounts take two 120 mm or two 140 mm fans, and the bottom supports three 120 mm or two 140 mm fans. Three included 120 mm fans and two 140 mm fans provide a baseline airflow that scales with additional radiators.
