LIAN LI Lancool 217 INF Mid Tower ATX Gaming Case

Infinity Mirror, Now Breathing

LANCOOL 217 INF continues our signature high-efficiency airflow design with an infinity mirror front panel for a striking visual effect, while dual tempered glass cutouts ensure ample airflow.

INFINITY MIRROR, TOTAL CONTROL

With L-Connect 3, users can wirelessly control fan speed and ARGB lighting, including the front panel’s infinity mirror. When paired with the L-Wireless controller, it delivers synchronized lighting effects across compatible devices for a seamless and immersive setup.

A built-in wireless receiver in the rear hub allows seamless control through L-Connect 3 and L-Wireless technology.

LIGHTING CONTROL, MADE SIMPLE

The top I/O panel integrates an M1 button for front panel lighting and an M2 button for fan lighting effects, allowing easy customization of illumination styles.
Users can choose between three lighting control methods: through L-Connect 3 (wireless controller required), via the I/O buttons, or by using motherboard sync.

MASSIVE AIRFLOW, EFFORTLESS COOLING

The LANCOOL 217 INF is equipped with high-performance front and rear fans, plus additional fan mounting options at the top and bottom of the chassis. This flexible airflow setup maximizes heat dissipation and ensures smooth, stable performance for all internal components.

The front fans come with a metal mesh dust filter that prevents dust intake and accidental fan contact. The filter can be easily detached for quick cleaning.

Independently tested by the PPLP Lab, the LANCOOL 217 INF delivers exceptional thermal performance, ranking among the top of its class. Its optimized airflow structure and powerful cooling capacity earned it the PPLP “S-Class” Thermal Performance Rating, proving its superior temperature management.

Flexible Installation Options

The LANCOOL 217 INF includes screws for 120 mm fan installation, allowing users to mount fans on the PSU shroud for additional airflow. Alternatively, two 120mm fans can be installed beneath the PSU cover to create more space and improve internal cooling flexibility.

FLEXIBLE DESIGN, VERSATILE LAYOUTS

The PCIe slot bracket can be turned 90 degrees to support vertical GPU mounting. In this setup, the bottom fan can be moved under the PSU shroud for a hidden look, giving users more flexibility when building their system.

RELOCATABLE I/O PANEL TOP OR BOTTOM

Choose top or bottom I/O placement to suit desktop or floor standing setups, giving you style and access your way.

MOTHERBOARD COMPATIBILITY

Supports motherboard sizes: EEB (width <330mm) / E-ATX (width <280mm) ATX/ Micro-ATX/ Mini-ITX.

Back-connect motherboard support: ATX, Micro-ATX.
