Lian Li B4-1X Vertical AeroDeck Mini-Tower Case with window, Black / Walnut

The Lian Li B4-1X Vertical AeroDeck is a conversion kit for the Lian Li x DAN B4 chassis. This kit changes the standard enclosure to a vertical orientation, altering how internal components draw air. This orientation isolates the graphics card, allowing it to draw air directly from outside the case rather than relying on standard internal circulation. Users can view their components through a 4 mm tempered glass side panel. The module features a steel frame with walnut accents and retains the case’s 21.3-litre volume while prioritizing direct GPU cooling.

The vertical layout increases the chassis’s liquid cooling capacity. The modified side bracket supports 240 mm, 280 mm, or 360 mm radiators for custom loops or all-in-one liquid coolers. Active cooling is provided by 120 mm fans (up to 1800 RPM, 64.2 CFM). The case accommodates CPU coolers up to 162 mm tall and power supplies up to 140 mm (SFX or ATX). Connectivity includes two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2 Type-C port, and a combo audio jack. Cable routing and an integrated dust filter are included.
