What the Lian Li O11 Vision-M Is
The Lian Li O11 Vision-M is a compact Micro-ATX case that combines a three-sided tempered glass design, dual-chamber layout, and improved airflow to give small form factor PC builders a clear view of premium components without sacrificing cooling performance. As a compact PC chassis, it shrinks overall volume by about 20% compared to the O11 Vision Compact while still supporting serious hardware, including long graphics cards, tall air coolers, and multiple radiators. This tempered glass case is aimed at users who want a small form factor PC that looks like a high-end display piece on the desk, with cables, power supply, and storage hidden out of sight. At the same time, it focuses on thermal efficiency, addressing common airflow issues that full-glass designs often face in Micro-ATX and Mini-ITX builds.
Triple-Glass Panoramic Design With Hidden Clutter
The O11 Vision-M continues the panoramic triple-side glass concept of the Vision series, turning your Micro-ATX build into a display from almost any viewing angle. Three tempered glass panels frame the main chamber, while a smart dual-chamber layout moves the PSU, storage, and most cable runs into a separate compartment. That separation keeps the visible space focused on your graphics card, cooling, and lighting, ideal for enthusiasts who want a compact PC chassis that still looks clean and intentional. An optional divider hides the top radiator and even tubing, keeping the viewing area uncluttered. Lian Li also provides 3D printing files, so users can design their own custom divider pieces to match a theme or branding, further extending the personalization potential of this small form factor PC platform.
Optional LCD Divider for Data and Style
One of the Vision-M’s standout customization options is the optional LCD divider that fits between the dual chambers. This add-on uses a 9.2-inch IPS panel with a 1920×462 resolution at 60Hz, delivering a bright 500-nit display that runs along the side of your main components. Through L-Connect 3, the screen can show system statistics, custom images, or even short videos, turning the divider into a live status bar or a themed design element. According to Lian Li, the screen also supports an offline mode that keeps showing the time and date when the PC is turned off. Because the LCD is sold separately, builders who prefer a simpler look can skip it and rely on the included divider or a custom 3D-printed piece instead.
Airflow, Cooling Capacity, and Thermal Gains
To address airflow limitations typical of full-glass Micro-ATX cases, the O11 Vision-M integrates ventilation directly into the top glass panel. This section can host a 360mm radiator up to 55mm thick, or up to three 120mm fans, while an additional side mount supports a 240mm radiator. In total, the case can house up to twelve 120mm fans plus a pre-installed 140mm intake fan that is positioned to feed extra air to the radiator. Lian Li states that the optimised layout can improve CPU temperatures by up to 4°C and GPU temperatures by up to 2.6°C compared to the O11D Mini V2 and O11 Vision Compact. For a compact PC chassis with three-sided glass, those gains are significant, giving small form factor PC builders more headroom for high-performance components and overclocked setups.
Compact Hardware Support and Positioning in the Market
Despite its reduced dimensions of 419.6mm (D) x 275.1mm (W) x 395.2mm (H), the Lian Li O11 Vision-M supports Micro-ATX and Mini-ITX motherboards, CPU coolers up to 162mm tall, power supplies up to 182mm long, and graphics cards up to 410mm, complete with an anti-sag bracket for horizontal mounting. Storage is covered in the second chamber with mounts for three 2.5-inch drives or a combination of one 3.5-inch HDD and one 2.5-inch SSD. Front-panel connectivity includes one USB 3.2 Type-C port, two USB 3.0 ports, and a 3.5mm audio jack. By blending a desk-friendly footprint, three-sided glass, strong cooling support, and optional LCD flair, the O11 Vision-M positions Lian Li as a leader in the premium compact chassis space for style-focused Micro-ATX builders.
