Lian Li Unveils the New Compact ATX Tower O11D MINI V2 PC Case

LIAN LI Industrial Co., Ltd., a leading manufacturer of chassis and PC accessories, announces the O11D MINI V2, a compact ATX tower that provides expanded hardware compatibility and better airflow with only a 2-liter increase in size compared to the original O11D MINI design. Now supporting full ATX motherboards, standard ATX PSUs, and radiators up to 360 mm, the O11D MINI V2 is also fully compatible with ATX Back-Connect motherboards. It features a 10° slanted bottom for enhanced GPU cooling, support for both standard and vertical GPU mounting with included adjustable anti-sag brackets, and a repositionable I/O module for flexible front panel ports and button access. The Flow variant of the O11D MINI V2 comes pre-installed with 5 x 120 mm reverse-blade fans, offering optimized airflow straight out of the box.

Minimal Size, Maximum Support
With only a 2-liter increase in volume, the O11D MINI V2 delivers significantly expanded compatibility. Thanks to a subtle side panel protrusion and an offset mounting bracket, the case now supports full-sized ATX power supplies without increasing its overall width. Internally, it accommodates ATX, microATX, and Mini-ITX motherboards, including ATX Back-Connect motherboards, while offering clearance for radiators up to 360 mm at the top and 240 mm on the side. The case supports up to three 120 mm fans at the bottom, two 120 mm fans on the side, one 120 mm at the rear, and up to three 120 mm or two 140 mm fans at the top, giving builders greater flexibility for high-performance configurations.

Optimized GPU Cooling and Mounting Flexibility
The O11D MINI V2 enhances GPU cooling with a newly designed 10° slanted bottom fan tray that directs airflow more effectively toward the graphics card for improved thermal performance. Whether users prefer a traditional horizontal setup or a vertical display for their GPU, the case supports both mounting options and includes dedicated adjustable anti-sag brackets for each configuration. The vertical mount bracket is positioned above the bottom fans and features a screw-based height adjustment to ensure precise alignment with GPUs of varying sizes. (PCIe riser cable sold separately.)

Relocatable I/O for Enhanced Flexibility and Airflow
The O11D MINI V2 features a modular I/O panel that can be mounted at the top or bottom of the case, allowing users to access ports more easily based on their setup. When installed at the top, the bottom of the case can be blocked off or left fully open, increasing airflow potential from the underside to help with GPU cooling and improving case portability.

Availability
The O11D MINI V2 is available on July 25, 2025, at an MSRP of $89.99 for the black or white version, and $99.99 for the O11D MINI V2 FLOW pre-installed black or white version with 5 x 120 mm reverse-blade PWM fans.
