Description
FLUX REAR
The Antec FLUX REAR ARGB is a next-generation ATX mid-tower gaming chassis engineered around Antec’s advanced F-LUX airflow platform, designed to deliver superior cooling performance for modern high-end systems.
This chassis features a unique front-mounted PSU chamber layout, allowing unobstructed airflow from the bottom intake directly to the GPU, dramatically improving graphics card cooling during gaming and heavy workloads.
Equipped with five high-performance PWM fans, including ARGB and reverse airflow fans, the FLUX REAR ensures optimal air distribution throughout the system. Its multi-directional ventilation system includes mesh front intake, bottom airflow channels, and top exhaust vents, creating a dedicated cooling path for maximum efficiency.
The case supports large GPUs up to 400mm, CPU coolers up to 180mm, and a 360mm radiator at the top, making it ideal for high-performance gaming PCs and workstation builds.
Additional premium features include tempered glass side panels, back-connect motherboard support for cleaner cable management, a GPU support bracket, and wood-style design accents, blending performance with a modern, premium aesthetic.
