LIAN LI and DAN Cases have teamed up to launch the latest B4-mATX, a 21.3-liter small form factor PC case designed for compact yet high-performance builds. Here’s a quick look at it.
The B4-mATX features a versatile design that supports both horizontal and vertical orientations, with the latter reducing desk space by up to 30%. It includes a rotatable AC inlet and swiveling cable bracket for cleaner cable management, while users can choose between a perforated mesh front panel for improved airflow or a real wood finish in walnut or beech, available in black or white.
For cooling, the case comes pre-installed with two slim 120mm exhaust fans and supports flexible configurations, including up to a 360mm side radiator with an SFX power supply or 240mm with a 140mm ATX PSU.
Despite its compact 21.3-liter footprint, it accommodates 358mm graphics cards, 162mm CPU air coolers, and includes a pre-installed adjustable GPU anti-sag bracket alongside support for 3.5-inch and 2.5-inch storage drives.
LIAN LI also offers an optional Vertical AeroDeck accessory, which enhances GPU airflow with support for up to three 120mm or two 140mm fans. It features tempered glass side panels, a magnetic dust filter, and matching real wood finishes to complement the B4-mATX Wood edition.
