2.2 Assembly Steps
- Disassembly: Carefully remove the side panels and top panel by unscrewing the custom countersunk screws. Keep track of all screws for reassembly.
- Motherboard Installation: Install your MATX or ITX motherboard onto the standoffs. Secure it with the appropriate screws.
- CPU Cooler Installation: Mount your CPU cooler, ensuring it does not exceed the 135mm height limit.
- Power Supply Installation: Install the SFX power supply into its designated bay. Route the power cables as needed.
- GPU Installation: Insert your graphics card into the PCIe slot. Ensure its length (max 310mm) and width (max 135mm) are within limits. Secure it with screws.
- Fan Installation: Install cooling fans in the designated locations (top, rear, bottom) to optimize airflow. Refer to Figure 4 for fan placement.
- Storage Installation: Mount your 2.5" SSD in the available slot.
- Cable Management: Due to the compact nature of the case, careful cable routing is essential to maintain good airflow and aesthetics. Utilize any available tie-down points.
- Front I/O Connections: Connect the front panel cables (USB 3.0, Type-C, power switch) to your motherboard.
- Reassembly: Once all components are installed and cables are managed, reattach the panels using the countersunk screws.

3. Operating Instructions
3.1 Powering On/Off
- To power on your system, press the metal power switch located on the front I/O panel.
- To power off, either shut down your operating system normally or press and hold the power switch for several seconds for a forced shutdown.
3.2 Front I/O Ports
The front panel provides convenient access to essential ports:
- USB 3.0 (5G): For high-speed data transfer with compatible devices.
- Type-C (10G): For high-speed data transfer and connectivity with USB-C devices.
- Metal Switch: Power button for system control.

4. Maintenance
4.1 Cleaning the Exterior
- Use a soft, dry cloth to wipe down the aluminum exterior.
- Avoid abrasive cleaners or solvents that may damage the finish.
4.2 Dust Management
- Regularly inspect the case for dust buildup, especially on mesh panels and fan intakes/exhausts.
- Use compressed air to clear dust from fans and internal components.
- For thorough cleaning, the panels can be removed as described in the assembly section.
5. Troubleshooting
If you encounter issues with your system built in the C26 case, consider the following:
- No Power: Ensure all power cables (PSU to wall, PSU to motherboard, CPU, GPU) are securely connected. Verify the power switch on the PSU is in the 'on' position.
- No Display: Check that the monitor cable is connected to the graphics card (not the motherboard integrated graphics, unless no discrete GPU is installed). Reseat the graphics card and RAM modules.
- Overheating: Verify that all case fans and CPU cooler fans are spinning correctly. Ensure proper airflow direction (intake/exhaust). Check for dust buildup obstructing airflow. Confirm CPU cooler is properly seated and thermal paste is applied.
- Component Fit Issues: Double-check component dimensions against the case specifications (GPU length, CPU cooler height). Ensure cables are not obstructing component installation or panel closure.
- Loose Connections: Re-verify all internal connections, including power, data, and front panel headers.
