The Lian Li B4-mATX Mesh is a testament to precision craftsmanship, co-developed with Daniel Hansen of DAN Cases to deliver a compact yet remarkably flexible chassis. Measuring at a compact 21.3-liter volume, this case is designed to house professional-grade components in a footprint that maximizes your desk space efficiency. Its modular design philosophy allows builders to adapt the layout to their specific needs, offering both horizontal and vertical configurations with the included rear feet, ensuring it fits perfectly into any workspace setup.
Broad Hardware Compatibility
Despite its small form factor, the B4-mATX defies expectations by accommodating robust hardware builds. The internal frame supports Micro-ATX motherboards and is designed for high-performance GPUs up to 358mm in length and 4 slots in thickness. Power supply support is equally flexible, accepting standard ATX units up to 140mm or space-saving SFX power supplies. For cooling, the case provides immense liquid cooling potential, supporting side-mounted radiators up to 360mm, enabling a high-end, silent, and overclocked system in a fraction of the space required by traditional mid-towers.
Flexible Cooling and Airflow Innovation
Airflow is prioritized through every stage of the B4-mATX design. The front-to-back airflow path is enhanced by a front mesh panel that balances aesthetics with unrestricted ventilation. The case ships with two pre-installed 120mm slim fans at the top to assist in heat exhaustion, while the side and bottom mounts allow for a dense array of additional fans to saturate the internal components with fresh air. Unique features like the reversible rear fan bracket, which can be angled to optimize heat extraction, demonstrate the meticulous attention to detail dedicated to keeping your internals running within optimal thermal limits.
Builder-Centric Features
Lian Li has simplified the assembly process with a suite of builder-friendly features. The tool-less removable panels ensure quick access to components, while the removable top and front brackets make cable routing and radiator installation significantly easier than typical SFF enclosures. Cable management is streamlined with multiple tie points around the PSU and top brackets, ensuring your final build looks as organized as it performs. Whether you are building an airflow-optimized powerhouse or a liquid-cooled artistic statement, the B4-mATX Mesh provides the structural integrity and modular freedom to realize your vision.
