Lian Li DAN B4 Vertical AeroDeck Mini-Tower Case with window, White

The Lian Li DAN B4 Vertical AeroDeck (White) is a conversion kit for the DAN Cases B4 Micro-ATX chassis. It mounts the graphics card vertically, directing airflow straight into the GPU cooler. The design supports Micro-ATX and Mini-ITX motherboards within a compact footprint. Featuring a white steel frame, a tempered glass panel, and wood veneer trim, it updates the case’s appearance while helping manage temperatures in dense builds.

The interior accommodates tower-style CPU coolers up to 162 mm tall. Two 120 mm exhaust fans are pre-installed, operating at up to 1800 RPM with an airflow of 64.2 CFM and 2.4 mmH2O static pressure. The case supports SFX or ATX power supplies up to 140 mm long. An integrated dust filter helps prevent particulate buildup, and dedicated cable routing keeps wires out of the main airflow paths.

• Side and top radiator support: Fits up to a 360 mm radiator at the top and 240, 280, or 360 mm radiators on the side bracket for liquid cooling.
• High-capacity fan layouts: Accommodates up to three 120 mm or 140 mm fans on the bottom and side panels, with single 120 mm mounts at the front and rear.
