The Regnum 400 Air is the home your components deserve — a proper mansion. It’s spacious, but without overwhelming your room (472×442×220 mm) and can easily house everything you need for work and more.

The interior of the case is airy and can be extremely windy thanks to the mesh front panel and the possibility of installing up to 8 fans — 4 black Stratus 120 PWM fans are already included in the package. The Regnum 400 Air can also fit a large radiator (240/280 mm on the top, 360 mm on the front) for the truly arctic environment for your treasures components.

The Regnum’s vast indoors allows you to install up to 4 disks — either 2× 2.5” and 2× 3.5”, or 4× 2.5”. It also accommodates even E-ATX motherboards, a 275 mm long PSU, and a GPU up to 370 mm. With enough room left to swing a cat!
