Lian Li B4-mATX Case Launches for Around $80, Prioritizes Vertical Space

Small form factor builders in China now have a compact option that prioritizes vertical space savings and tool-less assembly. Lian Li released the B4-mATX case on June 26, 2024, offering a modular design that helps users reclaim desktop area. The manufacturer claims the vertical layout increases desktop space utilization by up to 30 percent compared to traditional horizontal builds. This approach matters for users with limited desk real estate who still want to house a full-sized motherboard.

Modular chassis co-developed with DAN Cases hits Chinese market

The chassis supports mATX motherboards and features a 21.3-liter internal volume. Lian Li co-developed this design with DAN Cases to ensure structural integrity within the small footprint. The case accommodates 360mm all-in-one liquid coolers and 140mm ATX power supplies, which are less common in mini-ITX or compact mATX builds. This combination allows builders to use higher-end cooling and power components without requiring a larger enclosure.
