Lian Li
A compact mATX dual-chamber case with three tempered glass panels, a pre-installed 140 mm side fan, and support for a 360 mm top-mounted AIO
Option White
Struck-through versions exist but are not stocked here.
The Lian Li O11 Vision-M is a white mid-tower chassis built for Micro-ATX and Mini-ITX motherboards. Its three-sided tempered glass design puts components on full display while a dual-chamber layout separates the power supply from the main build area for cleaner cable routing. A single 140mm fan comes pre-installed in the right chamber to establish positive airflow from the start.
Front I/O provides two USB 3.0 Type-A ports and one USB 3.2 Type-C port alongside a single audio jack. The power supply mounts at the bottom and accepts units up to 182mm long, while the CPU cooler clearance stops at 162mm. Graphics cards up to 410mm in length will fit, but longer models exceed the internal limit.
The top panel cut-out supports radiators up to 360mm, making that dimension the deciding factor for liquid-cooling buyers. If your all-in-one cooler exceeds 360mm you must choose a different chassis; if it fits within 360mm the case accommodates a concealed AIO layout that keeps tubing hidden behind the modular divider.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
The Digital Edition adds a built-in 9.2" LCD screen while the Standard Edition does not; both share the same three-sided glass layout, dual-chamber layout and mATX support.
You can install any all-in-one cooler with a radiator up to 360 mm in the top chamber, where a glass cutout vents exhaust heat directly.
The port runs at 10 Gbps and is limited by the motherboard header you connect it to; most current boards deliver the full 10 Gbps.
