Lian Li B4 mATX Vertical AeroDeck White

The Lian Li B4-mATX X Vertical AeroDeck Case is a versatile cooling accessory designed to enhance graphics card airflow while complementing the compact, vertical configuration of the Lian Li B4-mATX chassis. The AeroDeck features tempered glass side panels that showcase fan side-frame lighting, creating a coordinated appearance for showcase gaming PC builds. Its expanded cooling capacity supports up to three 120mm fans or two 140mm fans, with fan thicknesses of up to 30mm, providing a dedicated airflow path to help improve GPU thermal performance. When configured with three 120mm fans, the AeroDeck can reduce graphics card temperatures by up to 4.6 degrees Celsius. An integrated PVC dust filter helps minimise dust accumulation while maintaining airflow, supporting cleaner operation over time. Designed specifically for the B4-mATX in its vertical orientation, the accessory integrates with the case's modular design to provide additional GPU cooling without compromising its space efficient layout. Installation requires repositioning the case's I/O module, and the AeroDeck is an optional accessory rather than a complete PC case. With its flexible fan support, integrated dust filtration and tempered glass construction, the Lian Li B4-mATX Vertical AeroDeck is an ideal upgrade for builders seeking improved graphics card cooling and a distinctive vertical PC presentation.
