DeepCool CL6600 ARGB Mid-Tower ATX Case - 360mm AIO, Black
The DeepCool CL6600 ARGB Mid-Tower ATX Case is designed for builders who want serious liquid-cooling performance without compromising interior organisation or airflow. Its modular split-chamber layout physically separates the radiator zone from the main component area, preventing heat cross-interference that conventional cases cannot avoid. It ships with a pre-installed 360mm ARGB AIO cooler and two reverse-blade bottom fans, so a high-performance thermal setup is ready from the first boot.
Why this product
Split-chamber layout isolates radiator heat
Separate airflow paths for the radiator zone and main component chamber prevent hot air from recirculating across heat-sensitive parts — a structural advantage over conventional single-chamber layouts.
360mm AIO cooler included out of the box
A pre-installed 360mm ARGB liquid cooler with an advanced pump running at 2500–3400 RPM and triple FDB radiator fans means the cooling system is already fitted and ready to run.
Dual bottom ARGB fans pre-installed
Two FL12R SE reverse-blade 120mm ARGB fans sit at the bottom, pulling in fresh air without crowding the interior and contributing to the lit aesthetic.
Supports GPUs up to 388 mm with front fans fitted
Long graphics cards fit comfortably, and a included GPU support bracket keeps heavy cards seated correctly during use and transport.
Tool-free panel removal for easy access
All panels detach without tools, and 35 mm of cable-routing space, Velcro straps, and tidy covers simplify management for any experience level.
Real wood accent and vertical grille front panel
Vertical grille bars provide natural ventilation and a visual rhythm, while a real wood finish element adds an organic contrast to the tempered glass and SPCC steel construction.

Best for
- Liquid-cooling enthusiasts who want a 360mm AIO included rather than sourced separately — the cooler, pump, and three FDB radiator fans are all pre-installed.
- Back-connect motherboard builders who need a case with explicit support for rear-connector ATX and Micro-ATX boards alongside a clean interior view.
- Builders with long GPUs — up to 388 mm with front fans fitted, and up to 413 mm without them, giving flexibility for high-end graphics cards.
- ARGB aesthetics builds where a lit interior matters — the pre-installed 360mm cooler and dual bottom fans both include ARGB lighting, visible through the tempered glass panel.
- Builders who prioritise cable management — 35 mm of routing space, Velcro straps, covers, and tool-free panels make the process accessible regardless of experience level.
Trade-offs
- Air-cooling builds only: the split-chamber design and included AIO are optimised for liquid cooling; builders who prefer large air coolers may not make full use of the layout.
- Ultra-compact desks: at 457.5 × 235 × 533.5 mm and 11.82 kg, this is a full mid-tower — not suited to tight spaces or weight-sensitive setups.
- E-ATX or XL-ATX motherboards: these form factors are not listed in the supported motherboard specifications.
- PSUs longer than 160 mm in ATX PS2 format: the PSU bay is rated to a maximum of 160 mm for ATX PS2 units; longer units will not fit.
CL6600 rethinks case design for the liquid-cooling era. By physically separating thermal zones and airflow paths, it prevents heat buildup and cross-interference that conventional layouts can't avoid. It also comes with an advanced 360mm liquid cooler and dual bottom ARGB fans, delivering strong performance and creating a vibrant interior.
SPLIT FOR PERFECT FLOW
CL6600 keeps things cooler with a modular split-chamber layout. It places the radiator in its own zone, creating separate airflow paths for heat-generating components and letting the whole system run at its best.
BALANCE IN LAYERS
A raised top chamber redefines the overall silhouette while keeping space organized. Vertical grille bars at the front provide natural ventilation and create visual rhythm, with real wood adding an organic finish to the clean, modern aesthetic.
*The wood grain pattern may vary depending on the actual product.
