The FLUX Rear features five pre-installed high-performance PWM fans. This includes three 140mm PWM ARGB fans and two 120mm PWM reverse fans, providing strong intake from multiple directions. Large ventilation openings on the bottom, PSU shroud, and side panels work with the mesh front panel and top exhaust vents to create a highly efficient airflow system that enhances overall cooling stability.
The recessed front panel increases air intake while reducing noise. The premium design incorporates a metal mesh front panel accented with real wood elements, giving the chassis a refined and modern aesthetic. Tool-free removal for the top, front, tempered glass, and metal side panels ensures convenient installation and maintenance.
The chassis supports a top 360mm radiator and variable rear fan installation. It accommodates ATX, Micro-ATX, and ITX motherboards, CPU coolers up to 180mm in height, and graphics cards up to 400mm in length. A built-in GPU support bracket helps prevent sag and improves long-term stability. The interior layout also supports back-connector motherboards, allowing for cleaner cable routing and improved unobstructed airflow.
Cable management is optimized with a rear compartment depth of 37mm and 33mm, rubber grommets, and Velcro straps. The FLUX Rear includes a 13A extension cable for stable PSU support and provides multiple routing options depending on PSU connector orientation. Additional features include a bottom dust filter, one 3.5 inch HDD bay, two 2.5 inch SSD bays, and an I/O panel with USB 3.0, USB-C 3.2 Gen 2, audio combo jack, and dust plugs.

Key Features:
• F-LUX Platform with five pre-installed PWM fans, including three 140mm PWM ARGB fans and two 120mm PWM reverse fans for powerful and efficient airflow
• Front-mounted PSU shroud architecture that provides unobstructed bottom airflow to deliver cool air directly to the GPU area
• Back-connector motherboard support for cleaner cable routing and improved airflow
