Build Like Never Before with the LIAN LI B4-mATX Mesh
Co-developed with the visionaries at DAN Cases, the LIAN LI B4-mATX Mesh in stunning white redefines what a small form factor chassis can accomplish. This meticulously engineered 21.3L case brings unparalleled modularity to the micro-ATX market, effectively bridging the gap between minimalist aesthetics and aggressive hardware support. Whether you prefer the traditional horizontal desktop presence or want to maximize your workspace by rotating it into a striking vertical tower, this case adapts instantly. Integrated rear feet and a brilliantly designed rotatable AC power inlet ensure that cables remain out of sight, regardless of how you choose to display your system.
Massive Hardware Capacity in a Compact Footprint
Do not let the sleek 21.3-liter volume deceive you. The B4-mATX is engineered to house the most demanding flagship hardware on the market. It seamlessly accommodates M-ATX and Mini-ITX motherboards while leaving vast expanses of clearance for next-generation graphics cards. You can confidently install colossal 4-slot GPUs up to 358mm in length, sliding them in effortlessly through the highly accessible removable front fan bracket. Furthermore, the chassis comes pre-equipped with a heavy-duty, adjustable GPU anti-sag bracket, guaranteeing your premium components remain perfectly level and protected during heavy gaming sessions. Power delivery is equally flexible, offering native mounting support for compact SFX units as well as high-capacity 140mm ATX power supplies.
Unrivaled Airflow and Liquid Cooling Versatility
Thermal throttling is a thing of the past with the advanced cooling architecture found within the B4-mATX Mesh. The high-porosity white mesh panel acts as a massive intake canvas, promoting an uninterrupted front-to-back airflow channel. Out of the box, you receive two premium 120x120x15mm slim fans pre-installed on the top bracket, capable of hitting 1800 RPM to rapidly exhaust heat while remaining neatly daisy-chained for minimal cable clutter. Enthusiasts looking to push thermal limits can populate up to nine total cooling fans across the top, sides, front, rear, and bottom. If liquid cooling is your preference, pairing the chassis with an SFX power supply unlocks support for massive 360mm or 280mm All-In-One radiators. Even standard air-cooling purists are rewarded with an innovative reversible rear fan bracket, allowing for CPU tower coolers towering up to 168mm.
Tool-Less Assembly and Pristine Cable Management
Every inch of the LIAN LI B4-mATX is optimized to make the build process a luxurious experience. The exterior panels detach without the need for a single tool, exposing the skeleton of the case for completely unobstructed access. A fully removable top fan bracket transforms the normally tedious task of routing the CPU 8-pin power cable into a frictionless process. Strategic tie-down points surround the PSU shroud, allowing builders to execute incredibly clean cable runs. The bottom is guarded by a premium magnetic dust filter, ensuring that your meticulously crafted PC interior remains pristine. Blending elegant design with raw functional power, the B4-mATX Mesh White represents the ultimate foundation for your next high-performance micro-ATX workstation or gaming rig.
