DeepCool CL660 WH is a premium ATX mid-tower PC case designed for optimal thermal performance with its innovative HyperSplit split-chamber layout. This white chassis physically separates thermal zones and airflow paths to prevent heat buildup and ensure efficient cooling. Featuring a raised top chamber dedicated to radiator/CPU cooling and a bottom chamber for other heat-generating components, it prioritizes clean airflow dynamics and component longevity.

The case comes equipped with two pre-installed FL12R SE 120mm reverse-blade ARGB fans in the bottom chamber for excellent intake airflow and customizable lighting effects. It supports extensive cooling configurations, including radiators up to 360mm in the top chamber and up to eight 120mm fans in total, making it ideal for high-performance air and liquid cooling setups.

Compatibility is flexible, supporting Mini-ITX, Micro-ATX, and ATX motherboards. The spacious interior allows GPUs up to 413mm (or 388mm with front fan installed) and CPU coolers up to 175mm in height. Standard ATX PSUs up to 160mm length fit comfortably. Cable management is enhanced with 35mm routing space, Velcro straps, and quick-release panels, providing a tidy build environment.

Additional features include a hidden pop-out headset hook, a tool-less GPU support bracket, and an I/O panel featuring two USB 3.0 ports, one USB Gen 2 Type-C port, and an audio/mic jack. Constructed with durable ABS, SPCC steel, and tempered glass, the CL660 WH offers both functionality and a visually appealing aesthetic with its vertical grille bars and front wood-trim panel.

Whether building a high-performance gaming rig or a workstation, the DeepCool CL660 WH is engineered to deliver superior airflow, versatile cooling options, and user-friendly building features.
