Lian Li A3-mATX, Small Form Factor Case, SFF Case, Small Form Factor Chassis, Mini Tower Chassis, microATX Gaming Case

Minimalist but Wildly Dynamic The Lian Li A3-mATX embraces simplicity, combining precision airflow with a design focused on essentials. Its gated front panel invites air into the case, guiding it toward the finely perforated mesh behind, a quiet current that nurtures the components within. Supporting both mATX and ITX builds, it offers multiple PSU mounting points, and depending on its position and type, dramatically influences the layout. This flexibility allows users to strategically plan minimalist builds while packing the case with high-performance components. Minimalism defines its form—a compact, adaptable structure that provides choice without dominating its surroundings. Though small in size, its modular design unlocks surprising capacity, effortlessly housing bold, high-performance builds. Designed in collaboration with Dan Cases, this case brings a unique blend of functional elegance and precision.

In Collaboration with DAN Cases


The A3-mATX is the result of a collaboration between Lian Li and Dan Cases, bringing together the expertise of two renowned brands. Dan Cases is known for its innovative approach to compact, high-performance case design, where efficiency and simplicity are key. Their influence in the A3-mATX is evident in its refined modularity and space utilisation, offering a unique blend of precision and flexibility. This partnership is significant because it merges Lian Li’s reputation for exceptional build quality with Dan Cases’ minimalist, highly functional designs. The outcome is a case that doesn’t just look good—it optimises every inch, offering a new standard of performance in a compact form.

A Canvas for Cooling

Harness the FlowThe Lian Li A3-mATX offers an impressively adaptable cooling system for its compact size. Mesh panels invite cool air into the case, with ample room for various configurations. It supports a 360 mm radiator on the top, 240 mm radiators on the side and bottom, and up to three 120 mm top fans or two 140 mm ones. The side panel can fit two 120 mm fans, while the bottom allows for two more. This range of cooling options gives you the freedom to fine-tune your setup, making it possible to build a highly efficient system without sacrificing space.

Adaptable Space For Storage

REMOVABLE SSD TRAYThe A3-mATX includes a removable SSD tray mounted on the PSU bracket, offering flexibility for storage placement. It supports two 2.5” SSDs and can be relocated as needed, keeping your build clean and organised.

BOTTOM DRIVE SPACEThe case also features a bottom mounting point for additional storage, accommodating either a 2.5” SSD or a 3.5” HDD. This space efficiently utilises the compact design while offering the freedom to choose your preferred storage solution.

Multi-Level PSU Orientation

STAGES OF POWERThe A3-mATX provides exceptional PSU flexibility, supporting ATX, SFX, SFX-L, and LIAN LI Edge PSUs (F1 to F4 levels) across multiple mounting positions. An offset bracket for ATX PSUs unlocks the ability to install longer GPUs at F2 and F2.5, maximising available space. For added versatility, the case allows for front installation of the ATX PSU, mounting it on the SSD bracket with the included standoff tool—giving you complete control over your build’s layout and cooling potential.

Extensive Modular Design & Clearance

complete controlThe PSU placement and type in the A3-mATX shape the entire build, offering unmatched control. Choosing between an ATX, SFX or Lian-Li EDGE PSU redefines GPU length, fan and radiator configurations, all within this compact case. An ATX PSU allows for longer GPUs, while an SFX PSU frees up space for extra cooling. The top fan layout, side fan placement, and radiator sizes adjust accordingly, offering flexibility that’s rare in mini towers. With support for a 360 mm top radiator and multiple side fans, the A3-mATX lets you fine-tune your build, no matter how ambitious.

Chassis Airflow
Date Issued: 20th Oct 2008

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.
