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

The Lian Li O11 Vision-M in White is a compact M-ATX mini tower case designed for builders who want showcase-quality aesthetics without sacrificing cooling headroom. Its defining feature is a three-sided tempered glass design — front, side, and top panels are all glazed — giving an unobstructed panoramic view of the system interior from virtually any angle. The case uses a dual-chamber layout: the main chamber houses the motherboard, GPU, and cooling hardware in full display, while a hidden secondary chamber neatly routes power supply cables, liquid cooling tubes, and storage, keeping the visible interior clean and organised. Despite its compact footprint, the O11 Vision-M accommodates both M-ATX and Mini-ITX motherboards, and its dual-chamber construction supports an ATX power supply up to 182 mm in length, so builders are not forced to choose a smaller PSU. GPU clearance extends to 410 mm, making even large flagship graphics cards viable, and an included adjustable anti-sag bracket — height-adjustable from the secondary chamber using the bundled tool — keeps horizontally mounted GPUs stable without restricting fan airflow. Cooling flexibility is a highlight: the top panel supports radiators up to 360 mm (three 120 mm fans), the side supports additional radiators within the main chamber, and the bottom and rear offer further fan mounting positions. The top tempered glass panel incorporates a precision cutout that maintains the panoramic aesthetic while allowing warm air to escape efficiently. A 140 mm fan comes pre-installed in the secondary chamber on a 4-pin PWM connector, dedicated to improving heat dissipation from the AIO radiator. In total, the chassis can accommodate up to 13 fans across the top, side, second chamber, bottom, and rear positions. Storage options include up to three 2.5-inch SSDs, or one 3.5-inch HDD plus up to two 2.5-inch SSDs, tucked out of sight in the secondary chamber. Five expansion slots provide PCIe flexibility. The front I/O panel includes a power button, one USB 3.0 Type-A port, one USB 3.2 port, and a combined audio jack. A bottom dust filter is included to reduce intake contamination.
