LIAN LI O11 Air EATX Mid Tower Cabinet (Black)

The Lian Li O11 Air is an E-ATX mid tower cabinet built around a dual-chamber architecture that separates the main component area from the power supply and cable routing zone. The front, top, and side intakes are covered in super-fine mesh panels, channelling fresh air directly to your components and creating a high-pressure positive-pressure environment when fully populated with fans. The case ships with two 140 mm front intake fans pre-installed and accommodates a wide range of additional cooling solutions. You can mount up to three 360 mm radiators simultaneously across the top, bottom, and side positions, with the front also accepting 240 mm, 280 mm, and 360 mm radiators, making the O11 Air well suited to enthusiast AIO or custom loop builds. Five magnetic dust filters — one each at the front, top, and bottom, plus two on the side panel — reduce the need for frequent cleaning without restricting intake airflow. The side panel is made of tempered glass secured by Lian Li’s patented two-bolt steel-piece glass mounting mechanism, providing an unobstructed view of the internals without tool-free rattle. Cable management is handled through a double-layer system: an angled motherboard tray combined with a rear cable management bar keeps wiring contained behind the partition. The drive caddy can be swapped to a lower position or replaced by an optional second PSU for dual-PSU workstation or server-style builds. The I/O panel on top includes two USB 3.0 Type-A ports, one USB 3.1 Gen 2 Type-C port, and HD Audio in/out. Eight expansion slots accommodate multi-GPU or high-profile add-in cards, and GPU clearance extends to 420 mm in length and 159 mm in height, covering virtually all current discrete graphics cards.
