PC Case DeepCool CL660 Black — ATX/Micro-ATX/Mini-ITX, Tempered Glass, 2x3.5 inch + 1x2.5 inch, Front 140 mm, Top/Rear 120-140 mm

DeepCool CL660 Black is a mid-tower PC case designed for ATX, Micro-ATX and Mini-ITX systems. The chassis features a tempered glass side panel and a split-chamber internal layout that separates the main component zone from the power and drive area to improve airflow. The case supports two 3.5" drives and one 2.5" drive, accepts standard PSUs (ATX/PS2) as well as SFX and SFX-L units, and includes two front USB 3.2 Gen 1 Type-A ports. Cooling options include support for a 140 mm front fan and 120–140 mm fans at the top and rear; the overall dimensions are 235 × 457.5 × 533.5 mm and the net weight is 10.02 kg.

Advantages

The split-chamber layout promotes targeted airflow by creating separate paths for heat-generating components and the power/drive area, which helps maintain lower internal temperatures. The tempered glass side panel provides a clear view of internal components while the steel and ABS construction keeps the structure rigid. Support for multiple fan sizes and radiator configurations offers flexibility for both air and liquid cooling setups. Tool-friendly storage options accommodate two 3.5" HDDs and one 2.5" SSD without occupying external bays, and the front I/O with two USB 3.2 Gen 1 ports enables fast peripheral connections.

Suitable for

• Building a mid-tower gaming or workstation PC with ATX, Micro-ATX or Mini-ITX motherboard
• Systems requiring separate airflow zones for GPU/CPU and PSU/storage
• Compact builds that still need support for multiple storage drives and standard PSUs
• Users planning to install 140 mm front cooling and 120–140 mm fans at top or rear

How to use

Install the motherboard according to its form factor (ATX, Micro-ATX or Mini-ITX) using the standoffs provided, then mount the PSU in the dedicated compartment and secure storage drives in the appropriate trays or brackets. Fit cooling fans or radiators in the front, top and rear positions as required by your thermal design, ensuring clearance for GPU length and CPU cooler height. Connect front-panel USB and power/reset switches to the motherboard headers, manage cables through the available routing channels, and close the tempered glass panel once all components are installed and secured.

Recommendations

For optimal airflow, configure the split chambers so that fresh air is drawn in through the front 140 mm fan(s) and exhausted via the top and rear 120–140 mm fans. When installing an AIO radiator in the front, verify clearance for GPU length and consider a push-pull fan arrangement on the radiator for improved heat dissipation. Use anti-dust filters on intake locations and perform periodic cleaning to maintain cooling performance.
