Original Press Release

LIAN LI Industrial Co. Ltd., a leading manufacturer of chassis and PC accessories, announces the O11 AIR MINI, available in black and white. The new small tower case features an airflow focus design with dense mesh front, top and side panels, 3 pre-installed PWM fans, support for a wide array of fans and radiators configurations, and enough clearance for CPU tower coolers up to 170mm tall. The O11 AIR MINI can support ATX power supplies, and thanks to its modular back panel, motherboards from Mini-ITX up to E-ATX.

Airflow Focused

With a combination of front, top, and right-side dense mesh panels, support for up to ten 120mm fans, and filtered opening at the bottom, the O11 AIR MINI offers unrestricted ventilation. The two pre-installed 140mm PWM fans at the front and a 120mm PWM fan at the rear ensures a good foundation for thermal management.

Small Yet High-Performance

Similar in size to the O11D MINI, the O11 AIR MINI can support ATX power supplies of up to 200mm in length, enabling power-hungry systems without limitations. A modular back panel, which can be reconfigured from a 7-expansion slot setup for ATX motherboards to a 5-slot configuration for M-ATX and ITX motherboards, allows the O11 AIR MINI to install graphics cards up to 362mm in length and high-performance CPU cooling towers up to 170mm in height.

Flexible Cooling Configurations

Depending on the back panel configurations and motherboard installed, the O11 AIR MINI features four mounting locations for 240 radiators, with three capable to support 280 radiators, support for up to ten 120mm fans, or six 140mm fans and four 120mm, ensuring enough cooling for even the most demanding hardware.
