Setup Instructions

1. Unboxing and Initial Inspection

Carefully remove the PC case from its packaging. Inspect the case for any signs of damage during transit. Retain all packaging materials for future transport or warranty claims.

2. Removing Side Panels

Locate the thumbscrews on the rear of the case securing the tempered glass side panel and the solid steel side panel. Unscrew them and carefully remove both panels. Place them on a soft, flat surface to prevent scratches.

6. Graphics Card and Expansion Card Installation

Remove the necessary PCI-E slot covers. Insert your graphics card or other expansion cards into the motherboard's PCI-E slots and secure them with screws.

7. Cable Management

Route all power and data cables through the designated cutouts and tie-down points behind the motherboard tray. This helps maintain optimal airflow and a clean aesthetic.

8. Connecting Front I/O Panel Cables

Connect the front panel cables (USB 3.0, HD Audio, Power SW, Reset SW, Power LED, HDD LED) to their corresponding headers on your motherboard. Refer to your motherboard manual for exact header locations.

Operating Instructions

Powering On

After all components are securely installed and cables connected, plug your PC into a power outlet and press the power button located on the top I/O panel of the case.

ARGB Fan Control

The pre-installed ARGB fans are connected to your motherboard. Lighting effects and fan speeds can be controlled via your motherboard's software utility (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync).

Maintenance

Dust Filter Cleaning

The LANCOOL 205M MESH includes magnetic dust filters on the top and bottom. Regularly remove and clean these filters to maintain optimal airflow and prevent dust buildup inside the case. Clean with compressed air or a soft brush.

General Cleaning

Wipe the exterior of the case with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the finish or tempered glass.

Troubleshooting

• PC Not Powering On: Ensure all power cables (24-pin ATX, 8-pin CPU, GPU power) are securely connected to the motherboard and components. Verify the PSU switch is in the 'ON' position. Check front panel power button connections to the motherboard.
• Fans Not Spinning/RGB Not Working: Confirm fan power cables are connected to the motherboard or fan controller. Ensure ARGB cables are properly connected to the motherboard's ARGB header. Check motherboard software for fan speed and RGB control settings.
• Component Fitment Issues: This case is designed for Micro ATX and Mini-ITX motherboards. While it accommodates many GPUs, very long or triple-fan graphics cards may have limited clearance. Similarly, large 280mm AIO liquid coolers may require specific mounting orientations (e.g., top mount) due to space constraints. Always verify component dimensions against case specifications before purchase.
• Poor Airflow/High Temperatures: Ensure all fans are spinning correctly and oriented for optimal airflow (front intake, rear/top exhaust). Clean dust filters regularly. Verify no cables are obstructing airflow paths.
