These are the same fan grills seen on some limited edition Lian Li cases. Match up your case or work off your own them with these anodized 140mm fan grills!
The Lian-Li PC-343 Modular Cube Power Supply Intake Filter is an OEM part for the Lian-Li PC-343 Modular Aluminum Cube Case. The part sits underneath the power supply unit and is designed to filter air being drawn into the power supply unit and case.
The Lian-Li V-Series Plus Power Supply Duct is an OEM Lian-Li part designed to vent the power supply's hot exhaust air away from the case and to cover up the fan for a sleeker look.
