Lian Li A3-mATX black (G99.A3X.00)
![]() |
Advanced Desktop gaming case with a focus on cooling flexibility in a compact form factor. The horizontal layout with dimensions of 322x194x443 mm creates a low-profile design for placement under the monitor, and the top-mounted power supply optimizes thermal isolation. A mesh front panel and side panel with a metal mesh enhance cooling efficiency. Supports micro-ATX motherboards with the option for vertical graphics card installation, allowing for impressive builds.
The Lian Li A3-mATX case features exceptional cooling capabilities — ten fan mounting positions supporting 140mm models provide unprecedented configuration flexibility for the desktop format. Three positions for 360mm radiators allow for the creation of an extreme liquid cooling system. The internal space accommodates graphics cards up to 415mm long — a feature surpassing many full-sized cases. Power supplies up to 220 mm and CPU coolers up to 165 mm are installed without restrictions. The bottom dust filter protects the main air intake. The front panel includes a modern USB-C 3.2 gen1 port, two USB 3.2 gen1, and an audio jack. A window for CPU cooler installation simplifies maintenance in the dense layout of the desktop case.
