Operating Instructions
Powering On
After connecting all necessary peripherals and the power cable to your PSU, press the Power Button on the front I/O panel to start your system.
ARGB Fan Operation
The Ant Esports 400 Air Mini comes with three pre-installed ARGB fans (two at the front, one at the rear) for immediate cooling and aesthetic lighting. These fans provide vibrant lighting effects. Please note that the RGB lighting on these pre-installed fans cannot be individually turned off or controlled via a dedicated button on the case itself. Control may be possible via motherboard software if your motherboard supports ARGB synchronization.

Fan Support and Airflow
The cabinet is designed for optimal airflow, supporting up to 7 x 120mm fans. This includes 2 x 120mm at the front, 2 x 120mm at the top, 2 x 120mm at the bottom, and 1 x 120mm at the rear.

Maintenance
Dust Filter Cleaning
The Ant Esports 400 Air Mini features a magnetic dust filter on the top panel. Regularly remove and clean this filter to prevent dust buildup inside the cabinet, which can impede airflow and component cooling.

General Cleaning
Use a soft, dry cloth to wipe down the exterior of the cabinet. For stubborn smudges on the tempered glass, a glass cleaner can be used sparingly on the cloth, not directly on the glass. Avoid abrasive cleaners or solvents.
Troubleshooting
If you encounter issues with your PC build, consider the following common troubleshooting steps:
- No Power: Ensure all power cables (PSU to wall, PSU to motherboard, CPU, GPU) are securely connected. Check the power switch on the PSU.
- Fans Not Spinning: Verify that all fan headers are correctly connected to the motherboard or fan controller. Check power connections to the PSU.
- No Display: Confirm that your monitor is connected to the graphics card (GPU) and not the motherboard's integrated graphics ports (unless you are using integrated graphics). Reseat the graphics card and RAM modules.
- Component Fitment Issues: Double-check the specifications for maximum component lengths (VGA card 280mm, CPU cooler 160mm) and motherboard compatibility (Micro-ATX, Mini-ITX).
- Front Panel I/O Not Working: Ensure the front panel cables are correctly connected to the motherboard headers.
For more specific component-related issues, refer to the respective component manuals (motherboard, GPU, PSU, etc.).
