Lian Li A3-mATX Overview

Sporting a clean and sophisticated look, the Lian Li A3-mATX Mini-Tower Case in black saves room on your desktop or entertainment center. For builders looking for a full, robust experience in a smaller form factor, the A3-mATX offers support for resource-hungry components without compromising performance.

Designed to leverage every inch of its compact design, the A3-mATX supports Mini-ITX and Micro-ATX motherboards as well as ATX power supplies. Four expansion slots accommodate graphics cards up to 16.3" in length and there is 6.4" of clearance for CPU coolers. While the A3-mATX sports a breathable design, up to ten 120mm fans or a 360mm radiator may be installed to enhance airflow and balance thermal performance. Connect essential devices such as controllers and external drives to the two USB-A ports and one USB-C port. Separate 3.5mm audio output and microphone input jacks enable easy communication for conference calls or gaming.

Fully Customizable, Fully Compatibility
With its relocatable PSU bracket, the A3-mATX allows you to build a PC tailored to your needs. All the panels (sides and top) are removable, giving you a clean 360° view of your internals, and the case can accommodate large components.
Adaptable Storage Solutions
The A3-mATX provides three drive bays to meet storage needs in a comprehensive build. The removable SSD tray uses the same mounting point as the PSU bracket and can be relocated as needed. The bottom of the case can hold one SSD or HDD.
Dan Cases Collaboration
Combining the design of Daniel Hansen from DAN Cases with Lian Li's manufacturing prowess, the collaboration brings the A3-mATX to life.

Awesome Case - Great For A Couch Gaming Build

By Joseph
Rated 5 out of 5

I'm Very Happy With It. Easy To Work In, Roomier Than You Would Think, Great Looks And All The Mesh Gives Good Airflow. Not A Ton Of Cable Management, But I Bought The Version That Is All Mesh On The Sides So None Of The Inside Is Visible Anyways. This Is For A Mini Living Room Couch Gaming Build, And It Turned Out Perfect. Lian Li Makes Great Cases, And B&H Delivered It Right On Time, Quickly And In Great Condition For A Great Price.

It’s a good starter case and for the price it’s a no brainer!
