4.2 Motherboard Installation

1. Install the I/O shield into the motherboard cutout at the rear of the case.
2. Align your Micro-ATX or Mini-ITX motherboard with the pre-installed standoffs. Ensure the screw holes on the motherboard align with the standoffs.
3. Secure the motherboard using the provided screws. Do not overtighten.

4.3 Power Supply Unit (PSU) Installation

1. Position the PSU into the dedicated compartment at the bottom rear of the case.
2. Secure the PSU from the rear of the case using the appropriate screws.
3. Route the necessary power cables through the cutouts to the main chamber for component connection.

4.4 Storage Drive Installation (HDD/SSD)

The case supports multiple storage configurations:

• 3.5" HDD: Install into the adjustable drive cage located under the PSU shroud. The cage can be repositioned for additional radiator or PSU space.
• 2.5" SSD: Mount SSDs to the dedicated mounting points on the motherboard tray or on top of the PSU shroud.

4.5 Graphics Card (GPU) Installation

1. Remove the necessary PCIe slot covers at the rear of the case.
2. Insert your graphics card into the appropriate PCIe slot on the motherboard.
3. Secure the graphics card with screws.

4.6 Fan and Radiator Installation

The TD300 Mesh offers versatile cooling options:

• Front: Supports up to 3 x 120mm fans or 1 x 360mm radiator. Two 120mm ARGB fans are pre-installed.
• Top: Supports up to 2 x 140mm fans or 1 x 280mm radiator.
• Rear: Supports 1 x 120mm fan or 1 x 120mm radiator.

Connect fan power cables to the motherboard or the included PWM/ARGB hub. Connect ARGB cables to the hub for synchronized lighting.

4.7 Cable Management

Utilize the cable routing cutouts and tie-down points behind the motherboard tray to organize cables. This improves airflow and aesthetics. The integrated PWM/ARGB hub helps centralize fan and lighting connections.

4.8 Final Assembly

1. Once all components are installed and cables are managed, reattach the rear side panel.
2. Carefully reattach the tempered glass side panel, ensuring it seats correctly, and secure it with the thumb screws.

5. Operating the PC Case Features

The Cooler Master TD300 Mesh case provides convenient front I/O ports and integrated ARGB control.

5.1 Front I/O Panel

The top front panel includes:

5.2 ARGB Lighting Control

The pre-installed ARGB fans and the integrated hub allow for customizable lighting effects. You can control the lighting in two ways:

• Via Motherboard Software: If the ARGB hub is connected to a compatible motherboard's ARGB header, you can use the motherboard's lighting control software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion) to synchronize and customize lighting.
• Via Case Button: If not connected to a motherboard ARGB header, or if you prefer, use the dedicated ARGB control button on the front I/O panel to cycle through pre-set lighting modes and colors.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your PC components.

• Dust Filters: The front mesh panel and top magnetic dust filter are designed to prevent dust ingress. Periodically remove and clean these filters using compressed air or by rinsing with water (ensure they are completely dry before reinstallation).
• Interior Cleaning: Use compressed air to blow dust out of internal components (fans, heatsinks, GPU fins) every few months.
• Exterior Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners.
• Tempered Glass: Clean the tempered glass panel with a microfiber cloth and a glass cleaner designed for electronics.

7. Troubleshooting

This section addresses common issues you might encounter.

Issue: PC does not power on after assembly.

Solution:

• Ensure the PSU is switched on and properly connected to the wall outlet.
• Verify all power cables (24-pin ATX, CPU, GPU, storage) are securely connected to the motherboard and components.
• Check that the front panel power switch cable is correctly connected to the motherboard's F_PANEL header. Refer to your motherboard manual for correct pinout.
• Confirm that the CPU and RAM are correctly seated.

Issue: ARGB fans are not lighting up or are not synchronized.

Solution:

• Ensure the ARGB cables from the fans are properly connected to the integrated PWM/ARGB hub.
• Verify the hub is receiving power (usually via a SATA power connector from the PSU).
• If using motherboard software, ensure the hub's ARGB cable is connected to a compatible 3-pin 5V ARGB header on the motherboard (not a 4-pin 12V RGB header).
• Try pressing the ARGB control button on the front I/O panel to cycle through modes.

Issue: Poor airflow or high temperatures.

Solution:

• Check that all case fans are spinning correctly and are oriented for optimal airflow (front intake, rear/top exhaust).
• Clean dust filters and internal components as described in the Maintenance section.
• Ensure proper cable management to avoid obstructing airflow.
• Verify CPU cooler and GPU cooler are properly installed and functioning.
