Lian Li O11 Vision-M M-ATX Mini Tower Case

The Lian Li O11 Vision-M (SKU: G99-O11VMX-IN) is a compact Mini-Tower case built around a dual-chamber architecture that separates the main showcase compartment from a hidden secondary chamber housing the power supply, liquid cooling tubes, and cable routing. This thoughtful layout keeps the tempered glass-enclosed interior clean and visually striking without sacrificing hardware compatibility. Three full panels — front, side, and top — are constructed from tempered glass, delivering an unobstructed panoramic view of the system interior. The top panel incorporates a precision cutout that allows airflow to pass through to a mounted radiator while preserving the continuous glass aesthetic. A pre-installed 140mm PWM fan in the second chamber provides supplemental airflow directed at the AIO radiator, improving heat dissipation efficiency. Despite its compact footprint, the O11 Vision-M accommodates M-ATX and Mini-ITX motherboards and supports full-length graphics cards up to 410mm, enabling even flagship GPUs to be installed comfortably. An included adjustable anti-sag bracket with a swiveling support platform stabilises horizontally mounted GPUs and can be adjusted from the second chamber using the supplied tool without obstructing fan airflow. Cooling flexibility is a core strength: a 360mm top-mounted radiator with up to three 120mm fans is supported, alongside side radiator options in the main chamber. Total fan support reaches up to 13 fans across the top, side, second chamber, bottom, and rear positions. ATX power supplies up to 182mm in length are accommodated in the isolated second chamber, supporting high-wattage units without compromising main-chamber presentation. Storage options include one 3.5-inch HDD plus two 2.5-inch SSDs, or up to three 2.5-inch SSDs, housed discreetly in the second chamber. A removable modular divider enables flexible interior configuration.
