PC case Lian Li LANCOOL III Midi Tower Black

The Lian Li LANCOOL III Midi Tower Black is a premium mid-tower PC case engineered for improved airflow and cooling. It ships with four pre-installed 140 mm PWM fans and fine mesh panels to direct ample airflow to high-end components. The case includes a hinged tempered glass side panel and a brushed aluminium front element, with a removable PSU mounting bracket for easier installation.

Advantages

The chassis supports extensive cooling configurations including up to ten 120 mm fans or a single 420 mm radiator in the main chamber. A multi-way front fan bracket provides four mounting positions for radiators or fans and uses a latch/handle mechanism for tool-free securing. Cable management is improved with toolless magnetic cable cover doors and organized layouts for hubs and cables, while multiple drive mounting locations accommodate up to 12 × 2.5" SSDs or combinations of 3.5" and 2.5" drives.

Suitable for

• High-performance gaming PC builds requiring strong airflow
• Custom water-cooling loops and radiators (up to 420 mm)
• Systems with multiple storage drives (SSDs and HDDs)
• Builders who prefer visible components behind tempered glass

How to use

Install the power supply either outside the chassis on the removable PSU bracket and slide it into place, or mount it directly in the PSU bay. Fit the motherboard and route cables behind the right-side chamber using the magnetic cable cover doors for neat cable management. Mount radiators or fans to the front bracket using one of the four bracket positions and secure the bracket with the latch/handle mechanism. Install storage drives in the provided mounting locations and connect them to the motherboard and PSU.

Recommendations

For optimal cooling performance, maintain unobstructed airflow through the fine mesh panels and use the supplied 140 mm PWM fans in a balanced intake/exhaust configuration. When installing large radiators or multiple fans, ensure sufficient clearance for the chosen motherboard and CPU cooler heights.
