Lian Li has introduced the O11 Vision-M, a compact microATX chassis that improves the panoramic triple-side glass design’s airflow and space efficiency. This model retains the visual appeal of the O11 Vision series, leveraging a dual-chamber layout to hide any boring parts, such as cables, PSU, and storage.
The O11 Vision-M is designed to address the airflow limitations commonly associated with full-glass cases. For instance, the Vision-M features ventilation holes on one part of the top-glass panel, capable of supporting large and thick AIO liquid coolers. To maintain a clean look, the radiator can be covered by an optional divider that separates the two chambers. The layout is configured in a way to hide even the tubing from the viewing area for an impeccable presentation.
This divider can also be equipped with an optional 500nits LCD screen, powered by a 9.2in IPS panel rocking a 1920×462 resolution at 60Hz. The display can show custom images, videos, or system information, handled through L-Connect 3. This screen also supports an offline mode that activates when the PC is turned off, showing the time and date. If this add-on isn’t to your taste or you prefer something different, Lian Li provides 3D printing files that should allow you to create your own divider.

Despite its smaller 419.6mm (D) x 275.1mm (W) x 395.2mm (H) dimensions, which represent about a 20% volume reduction compared to the O11 Vision Compact, the Vision-M uses the available space efficiently to support plenty of hardware. Starting with cooling, it offers room for up to 12 120mm fans plus one pre-installed 140mm intake fan. Five of these can be replaced by a 360mm radiator up top and one 240mm radiator on the side. The former can be up to 55mm thick.
For the main components, we have space for microATX or Mini-ITX motherboards, 162mm height CPU coolers, 182mm PSUs, and 410mm long graphics cards. The latter have access to a dedicated anti-sag bracket for horizontal installation. In the second chamber, we find room for storage sufficient for three 2.5in drives or one 3.5in HDD plus one 2.5in SSD.

The built-in 140mm fan is specifically positioned to provide additional airflow to the radiator, improving the overall liquid cooling efficiency. According to Lian Li, the Vision-M’s 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.
Lastly, in terms of connectivity, you will find one USB 3.2 Type-C, two USB 3.0, plus a 3.5mm audio jack.

The O11 Vision-M is available at £59.99 and £64.99, respectively, for the black and white versions, backed by a one-year warranty. The LCD screen is sold separately at £59.99, which is a good thing as it would have unnecessarily inflated the price of the case for those who don’t care about it.
