The DeepCool CL660 redefines PC case design for modern liquid cooling setups by featuring a modular split-chamber layout that physically separates thermal zones and airflow paths to prevent heat build-up and optimize cooling efficiency. Crafted with a combination of ABS, SPCC, and tempered glass, this mid-tower ATX case marries robust performance with elegant aesthetics, highlighted by real-wood decorative side trims (natural wood grain may vary).

Key cooling highlights include two pre-installed FL12R SE reverse-blade 120mm ARGB fans mounted at the bottom for fresh-air intake and vibrant illumination without sacrificing interior space. The case supports up to eight 120mm fans in total and radiators up to 360mm at the top, allowing ample customization for advanced cooling solutions.

Compatibility extends to Mini-ITX, Micro-ATX, and ATX motherboards with generous build capacity such as GPU clearance up to 413mm (or 388mm with the front fan installed) and CPU coolers up to 175mm tall. It accommodates multiple PSU form factors including ATX PS2, SFX, and SFX-L with a maximum PSU length of 160mm.

Designed for ease of assembly, the CL660 features quick-release, tool-free removable panels, Velcro cable straps, and 35mm cable routing space for neat builds. Additional convenience is provided by a hidden pop-out headset hook, a GPU support bracket, and a front I/O panel with 2× USB 3.0 ports, 1× USB Gen2 Type-C, and audio/mic jacks.

Measuring 457.5×235×533.5 mm and weighing approximately 10.02 kg, this case strikes an ideal balance between compactness and rich features for gaming, streaming, and high-performance PC builds.
