It features a sleek black design, supports ATX power supplies located at the bottom, and comes with three pre-installed 120 mm front fans.

## Long description

The CMP 520 case features an asymmetrical front panel that highlights three pre-installed 120mm ARGB fans as a central visual and functional element. A mesh geode-style front panel provides generous airflow intake while helping to filter dust. The interior is finished in full black and includes a PSU cover that conceals cables and supports various PSU orientations.
Advantages
Three 120mm ARGB fans are installed out of the box to deliver balanced airflow and addressable RGB illumination. The mesh geode front enables high air intake and improved dust control. Support for multiple fan and radiator placements allows flexible cooling configurations. A ventilated PSU shroud accommodates both active and passive-cooled power supplies and helps keep the build tidy. Compatibility with larger GPUs and tall CPU coolers leaves room for future upgrades.
Key specifications
Included fans: 3 × 120mm ARGB
Maximum GPU length: up to 350 mm
Maximum CPU cooler height: up to 161 mm
Fan support: up to 6 fans total
Radiator support: front, top and rear (various sizes depending on configuration)
Front panel: mesh geode design for increased intake and dust filtration
Interior finish: full black coating with PSU cover
PSU shroud: ventilated, supports multiple PSU orientations and cooling types
How to use
Install the motherboard, power supply and components following the case manual and manufacturer guidelines. Connect the pre-installed ARGB fans to the motherboard ARGB header or to an ARGB controller, and configure lighting through your motherboard software or compatible controller. Plan radiator and fan placement according to your cooling needs and component clearance limits: ensure the chosen GPU and CPU cooler fit within the specified 350 mm and 161 mm limits. Route cables beneath the PSU cover and behind the motherboard tray for improved airflow and a clean appearance.
Recommendations
For optimal cooling balance, use a push–pull configuration when installing multiple fans on the radiator and maintain regular dust cleaning of the mesh front panel. Verify ARGB compatibility with your motherboard or controller before connecting to ensure proper lighting control.
