Lian Li B4-mATX Wood in Black combines high-performance small-form-factor design with a warm, modern aesthetic in a 21.3-litre footprint.

Refined Real Wood and Mesh Aesthetic
Crafted with authentic walnut wood trim on the front panel and fine steel mesh side panels, the chassis balances premium furniture-inspired design with direct ventilation. The dark finish provides a sophisticated, stealthy backdrop for your build, while tool-less panel access makes installation and maintenance quick and effortless.

Versatile Dual-Orientation Layout
The chassis adapts smoothly to your desk layout by supporting both traditional horizontal and space-saving vertical configurations. Rotating the case vertically reduces its desk footprint by up to 30%, supported by integrated rear feet, a rotatable AC power connector, and a low-profile routing system providing 52mm of rear cable clearance.

Out of the box, the case includes two pre-installed 120mm slim black fans at the top and supports up to 9 fans in total across the chassis. For liquid cooling configurations, the side bracket accommodates 240mm, 280mm, or 360mm radiators up to 52mm in total thickness, while air coolers up to 165mm tall are fully supported.
