What the O11 Vision-M Is and Who It’s For
The Lian Li O11 Vision-M is a compact Micro-ATX chassis that combines three-sided tempered glass panels with a dual-chamber layout and tuned airflow, giving builders a compact PC case that highlights hardware aesthetics without sacrificing cooling performance or practical component support. Aimed at Micro-ATX and Mini-ITX users, it shrinks the familiar O11 Vision concept into a roughly 20% smaller volume than the O11 Vision Compact, yet keeps room for serious hardware. The dual-chamber design hides the PSU, storage, and bulk of the cables, so the main chamber remains a clean gallery for your GPU, motherboard, and cooling hardware. This makes the O11 Vision-M a strong option for mid-range gaming or creator rigs that want both style and sensible thermals, instead of choosing between full-glass looks and realistic airflow in a compact PC build.

Three-Sided Tempered Glass and Dual-Chamber Presentation
The headline feature of the O11 Vision-M is its panoramic triple-side tempered glass design: front, side, and most of the top are clear, creating an almost aquarium-like view of your components. By pushing the PSU, 2.5in / 3.5in storage, and cable clutter into a second chamber, the case keeps that glass volume focused on the parts you want to see. The result is a Micro-ATX chassis that behaves like a premium display case, ideal for colorful custom loops, high-end air coolers, and RGB-heavy setups. Lian Li even shapes the interior around clean sightlines, hiding radiator tubing and mounting points behind a divider so the main chamber looks tidy from any angle. For builders chasing a modern tempered glass PC with minimal visual noise, this design places presentation first without turning the build process into a fight against visible cables.
Optional LCD Divider and Customization Potential
A standout twist in this O11 Vision-M review is the optional internal divider that can house a wide IPS LCD. This 9.2in panel runs at 1920×462 resolution and 60Hz with a rated brightness of 500 nits, turning a structural part of the case into a customizable display. Through Lian Li’s L-Connect 3 software, the screen can show system stats, custom images, or looping videos. It even supports an offline mode that keeps time and date visible when the PC is shut down. As the divider already hides tubing and cabling, the LCD feels integrated rather than tacked on. Importantly, it is sold separately, so buyers who do not want an embedded display are not forced to pay for it. Lian Li also provides 3D printing files, letting modders design their own dividers and build themes around them.
Airflow, Cooling Capacity, and Thermal Improvements
Unlike many glass-heavy compact PC cases, the O11 Vision-M is built to move air. One section of the top tempered glass panel is perforated, allowing direct airflow to radiators and fans mounted above the main chamber. Inside, there is support for up to twelve 120mm fans plus a pre-installed 140mm intake fan, while radiator options include a 360mm unit up top (up to 55mm thick) and a 240mm on the side. The built-in 140mm fan is positioned to feed the radiator area, improving liquid cooling efficiency. According to Lian Li, this optimized layout can lower 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. That gives the triple-glass design credible thermal performance, rather than treating airflow as an afterthought.

Hardware Support and How It Compares to Other Compact Cases
For a reduced footprint of 419.6mm (D) x 275.1mm (W) x 395.2mm (H), the O11 Vision-M fits a surprising spread of hardware. It supports Micro-ATX and Mini-ITX motherboards, CPU coolers up to 162mm tall, PSUs up to 182mm long, and graphics cards up to 410mm with an included anti-sag bracket. Storage options cover three 2.5in drives or a mix of one 3.5in HDD and one 2.5in SSD in the rear chamber. Front I/O includes one USB 3.2 Type-C, two USB 3.0 ports, and a 3.5mm audio jack. Compared with many compact PC cases that trade visibility for airflow or vice versa, the O11 Vision-M leans into the trend of premium tempered glass panels while still offering tuned cooling and strong component support, making it well suited to mid-range gaming or creative rigs with Micro-ATX boards.
