Colour · Black
The B4-mATX is Lian Li's compact small-form-factor chassis, co-developed with Daniel Hansen of DAN Cases. It squeezes full micro-ATX motherboard support and a long, multi-slot graphics card into a tidy 21.3-litre steel enclosure that looks just as at home on a desk as it does under one.
This Wood Edition ships with a genuine real-wood front panel for a warm, refined finish, with the option to swap in a mesh panel for an airflow-first look. The dual-orientation design lets you stand the case vertically or lay it horizontally to suit your space.
Thoughtful internal layout leaves room for a tall air cooler or a large radiator, a full-size ATX power supply, and modern storage, while a clean modern I/O keeps fast USB within easy reach.
