## Long description

The Lian Li O11 AIR MINI Tower Black is a compact PC case engineered for high airflow in a small footprint. It supports ATX, Micro-ATX and Mini-ITX motherboards with modular back panels and offers space for multiple fan and radiator configurations. The case ships with two 140 mm PWM front fans and one 120 mm PWM rear fan, and provides clearance for large air coolers as well as room for AIO radiators.
Advantages
The O11 AIR MINI uses super-fine mesh panels on the front, top and side to maximise intake and exhaust airflow while acting as a dust filter. Its interior layout is spacious enough for different fan and radiator placements, supporting both air cooling (up to 170 mm tower cooler height) and AIO watercooling (compatible with 240 mm or 280 mm radiators at top, side or bottom). The case is available in a black brushed aluminium finish with tempered glass side panel for easy maintenance and component visibility. Two front 140 mm fans and one rear 120 mm fan come pre-installed to simplify initial setup.
Suitable for
Compact gaming or productivity builds requiring strong airflow
Air-cooling systems with tall tower coolers (up to 170 mm)
Custom AIO watercooling with 240 mm or 280 mm radiators
ATX, Micro-ATX or Mini-ITX motherboard configurations

How to use
Install the appropriate modular back panel for your motherboard (7-slot for ATX, 5-slot for smaller boards) before mounting the motherboard. Place storage drives in the dedicated 3.5" or 2.5" bays and route cables behind the motherboard tray for better airflow. The case’s fine mesh panels are designed to be left in place; ensure front, top and side fan positions match your chosen cooling setup (air or AIO) and connect PWM fans to motherboard headers or a fan hub. For AIO installations, select radiator mounting positions that do not conflict with other components and secure radiators using the provided mounting points.
Usage recommendations
Maintain the mesh panels by periodically cleaning them to prevent dust buildup and preserve airflow efficiency. When using high-performance GPUs or overclocked CPUs, prefer multi-fan intake and exhaust configurations and verify clearance for 240/280 mm radiators before purchase.
