This image highlights the internal "Matrix design" of the chassis, which facilitates convenient wire organization and installation of hardware such as the CPU cooler. It also shows the compatibility with long graphics cards.

2. Motherboard Installation

Install your Micro ATX (mATX) or Mini-ITX (ITX) motherboard onto the designated standoffs within the chassis. Secure it with the appropriate screws.

3. Power Supply Unit (PSU) Installation

The C+Max supports ATX power supplies up to 140mm in length, as well as SFX/SFX-L PSUs. Mount your chosen PSU in the designated ATX back mount area. Ensure proper cable routing.

4. Cooling System Installation

The case supports various cooling configurations:

• Liquid Cooling: Up to a 240mm All-In-One (AIO) liquid cooler can be installed.
• Air Cooling: Air coolers with a maximum height of 162mm are supported.
• Fans: The case supports 12cm fans (up to 2 on top, 2 on bottom) and a 9cm fan on the front (if no HDD is installed).

7. Cable Management and Final Assembly

Route all cables neatly to ensure optimal airflow and aesthetics. Once all components are installed and cables managed, reattach the side panels and top panel.

Operating Instructions

After successful assembly, connect your peripherals (monitor, keyboard, mouse) and power cable to the system.

Powering On/Off

Press the aluminum alloy power switch located on the front I/O panel to power on your system. The switch has a built-in LED indicator. To power off, use the operating system's shutdown function or press and hold the power button for a few seconds for a forced shutdown.

Front I/O Ports

The front panel provides convenient access to:

• 1 x USB 3.0 Port
• 1 x Type-C 10G Port
• Power Switch with LED Indicator

Maintenance

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

Dust Management

The C+Max case includes a dust proof net. Periodically clean the dust filters and internal components using compressed air or a soft brush to prevent dust buildup, which can impede airflow and cooling efficiency.

Cleaning

Wipe the exterior of the case with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish. For the tempered glass panel, use a glass cleaner and a microfiber cloth.

Troubleshooting

This section addresses common issues you might encounter.

System Not Powering On

• Ensure the power cable is securely connected to both the PSU and the wall outlet.
• Verify that the power switch on the PSU (if present) is in the 'ON' position.
• Check all internal power connections, including the 24-pin motherboard connector and CPU power connector.
• Confirm that the front panel power switch cable is correctly connected to the motherboard's front panel header.

Overheating Issues

• Ensure all case fans are properly installed and spinning.
• Verify that the CPU cooler (air or AIO) is correctly mounted and making good contact with the CPU.
• Clean dust filters and internal components regularly to maintain optimal airflow.
• Check for proper cable management to avoid obstructing airflow paths.

Graphics Card Not Detected / Display Issues

• Ensure the graphics card is fully seated in its PCI-E slot.
• Verify that all necessary power cables are connected from the PSU to the graphics card.
• Check that the display cable (HDMI, DisplayPort, etc.) is securely connected to both the graphics card and the monitor.
