PC Case Lian Li LANCOOL III Midi Tower White

The Lian Li LANCOOL III Midi Tower White is a mid-tower PC chassis designed for strong airflow and flexible cooling configurations. The case features fine mesh panels, tempered glass side panels and a white powder-coated exterior. It ships with multiple pre-installed 140 mm PWM fans and supports a wide range of cooling options including air, AIO and custom water cooling, plus extensive storage and cable-management solutions.

Advantages

The LANCOOL III offers improved thermal performance through fine mesh intake at the front, top and lower side panels and multiple pre-installed 140 mm PWM fans. Hinged tempered glass and removable panels provide easy access to internal components. The case supports large cooling setups — up to 10 × 120 mm fans or a 420 mm radiator in the main chamber — plus modular PSU-shroud options and reversible front I/O for flexible installation. Storage capacity and cable routing features are extensive, including toolless magnetic cable cover doors and an adjustable sliding cable cover.

Suitable for

• Gaming PC builds requiring high airflow and component visibility
• Air-cooling setups with tall CPU coolers (up to 185 mm clearance)
• AIO liquid cooling with up to 420 mm radiator support
• Custom water-cooling systems with multiple large radiators (support for up to three 360 mm radiators)
• Systems needing multiple SSD/HDD configurations (up to 12 × 2.5" SSDs or 4 × 3.5" HDDs + 8 × 2.5" SSDs)

How to use

Open the hinged tempered glass side panels for unobstructed access to the interior. Install the motherboard and route cables through the right-side chamber, using the magnetic cable cover doors for neat routing. Mount the PSU using the removable PSU bracket outside the chassis and slide it into place. Fit storage drives in the available mounting locations and install fans or radiators on the modular front, top and side brackets according to the chosen cooling configuration. Use the removable top fan bracket if additional clearance for a thick radiator/fan combo is required.

Recommendations

For optimal airflow, keep the fine mesh intakes unobstructed and consider the optional magnetic dust filter kit if operating in dusty environments; note that added filtration will reduce raw airflow. When installing a vertical GPU or a custom water loop, check clearance and mounting slot alignment before final assembly.
