The realm of small form factor computing is constantly evolving, but sometimes, the biggest revolution comes not from shrinking components, but from rethinking their physical space. Enter Lian Li, the design powerhouse known for pushing boundaries, with their latest offering: the B4-mATX chassis.
This isn’t just another computer case; it’s a versatile workspace designed to defy traditional limitations. Co-developed with Dan Cases, the B4-mATX introduces a small form factor that doesn’t just save space—it changes how you interact with your PC.
The core genius of the design lies in its dual orientation capability. Whether you need a compact desktop powerhouse or a space-saving tower, the B4 case rotates 90 degrees seamlessly. In vertical mode, users can achieve an impressive reduction in footprint, cutting the required desk space by up to 30%.
To manage this flexibility, smart engineering is embedded throughout. The chassis features a rotatable AC inlet that adapts instantly to either configuration, allowing users to choose whether to face the intake outward for easy cable access or inward to absorb any excess length, ensuring pristine airflow regardless of orientation.
Cable management is also a major focus, aiming to create an organized environment. A clever swivelling cable bracket positioned below the PCIe slots keeps all rear I/O cleanly flush against the case, providing up to 52mm of vital connector clearance. This attention to detail ensures that complexity doesn’t compromise aesthetics.
Aesthetically, Lian Li offers options for every taste. The enclosure comes in sleek black mesh or stunning real wood finishes—walnut or beech—all paired with clean white options. This blend of performance and natural material instantly elevates the B4-mATX from mere hardware to a statement piece.
Inside this compact shell, cooling is handled proactively. The case ships equipped with two slim exhaust fans ready to deliver cool air. It supports ambitious builds, accommodating graphics cards up to 358mm across four slots and CPU coolers up to 162mm tall (or 168mm if the side bracket is removed).
Power solutions are also flexible, with dedicated brackets available for both SFX and ATX power supplies. This allows enthusiasts to choose their cooling paths; an SFX unit opens the door to massive radiators up to 360mm, while the ATX option still offers a respectable 240mm capacity.
For those looking to push the boundaries even further, an optional accessory called the B4-mATX Vertical AeroDeck is available. This add-on brings tempered glass panels and expands cooling potential by allowing the addition of up to three 120mm or two 140mm fans.
With pricing starting at just $69.99 for the black Mesh version and reaching up to $89.99 for the premium white Wood model, the B4-mATX positions itself as an incredibly accessible and highly versatile entry into the SFF case market. It proves that cutting-edge design doesn’t have to come with a hefty price tag.
