## Long description

The Lian Li B4-mATX Mini Tower PC case in white and wood is a compact and versatile chassis co-developed with DAN Cases. Featuring a unique aesthetic that combines clean white finishes with natural wood elements, this mini tower is engineered to support Mini-ITX and Micro-ATX motherboards. It offers flexible cooling configurations, internal storage bays for 2.5-inch and 3.5-inch drives, and accessible front I/O ports including USB Type-C and USB 3.0. Designed for modern desktop setups, it balances efficient space usage with distinct styling.
Advantages
This PC case provides exceptional hardware compatibility within a space-saving volume, supporting long graphics cards, standard power supplies, and liquid cooling radiators. Its modular structure includes removable brackets and tool-less panels that simplify the installation and cable management processes. The chassis supports both horizontal and vertical layout orientations, allowing users to optimize their desk space usage. Enhanced cooling performance is achieved through multiple fan mounting options, pre-installed slim top fans, and flexible intake configurations.
Suitable for
Building compact gaming or workstation desktop systems
Setups requiring Mini-ITX or Micro-ATX motherboards
Users looking for a blend of modern white finishes and natural wood aesthetics

When it may not be suitable
This mini tower case may not be suitable for users who require Full Tower or Mid Tower dimensions to house extended E-ATX motherboards or massive custom water-cooling loops with multiple large reservoirs. Additionally, builders planning to use very thick multi-slot graphics cards should carefully verify bottom fan and radiator thickness clearance limitations before assembly.
