4. Setup
Careful planning and execution are crucial when building a PC in a Mini-ITX case due to space constraints. Always refer to the manuals of your individual components for specific installation instructions.
- Preparation: Unpack the case and all components. Ensure you have all necessary tools, including screwdrivers, cable ties, and thermal paste. Work on a clean, static-free surface.
- Panel Removal: Carefully remove the tempered glass side panels and any other removable panels as shown in Figure 2.5 to gain access to the interior.
- Motherboard Installation: Install your Mini-ITX motherboard into the designated area. Secure it with the provided screws.
- CPU and Cooler Installation: Install your CPU and CPU cooler onto the motherboard before mounting the motherboard into the case, if possible, to simplify the process. Ensure proper thermal paste application.
- Power Supply Installation: Mount your power supply unit (PSU) in the rear mount location. Route the necessary cables through the case's cable management cutouts.
- Storage Drive Installation: Install your 3.5-inch or 2.5-inch storage drives into the available mounting bays.
- Graphics Card (GPU) Installation: Install your graphics card. The i100 Pro supports vertical GPU mounting, which typically requires a PCI-e riser cable (refer to Figure 2.4). Ensure the riser cable is securely connected to both the motherboard and the GPU.
- Fan/Radiator Installation: Install any additional cooling fans or liquid cooling radiators according to the case's mounting points and your desired airflow configuration (refer to Figure 2.8).
- Cable Management: Route and secure all cables to ensure optimal airflow and a tidy interior. Use cable ties to bundle cables.
- Final Assembly: Reattach all panels, ensuring they are securely fastened.
5. Operating
Once your PC is fully assembled within the Jonsplus i100 Pro case, operating it is straightforward:
- Power Connection: Connect the power cable from your power supply to a wall outlet or surge protector.
- Peripheral Connections: Connect your monitor, keyboard, mouse, and any other peripherals to the appropriate ports on your motherboard and graphics card.
- Power On: Press the power button located on the front I/O panel of the case.
- System Monitoring: Monitor your system's temperatures and performance using appropriate software to ensure stable operation, especially during demanding tasks like gaming.
6. Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your PC components.
- Dust Cleaning: Periodically clean dust from the interior of the case and components. Use compressed air to blow out dust from fans, heatsinks, and dust filters.
- Dust Filters: The Jonsplus i100 Pro includes removable dust filters (refer to Figure 2.5). Clean these filters regularly by rinsing them with water and allowing them to dry completely before reinstallation.
- Cable Management Check: Occasionally check cable routing to ensure no cables are obstructing airflow or fan operation.
- Panel Security: Ensure all panels, especially the tempered glass, are securely fastened to prevent vibration or accidental damage.
7. Troubleshooting
If you encounter issues with your PC build, consider the following common troubleshooting steps:
- No Power: Ensure the power supply switch is in the 'ON' position, the power cable is securely connected, and all internal power connections (24-pin ATX, 8-pin CPU, GPU power) are properly seated.
- No Display: Verify that your monitor is connected to the graphics card (not the motherboard's integrated graphics ports, unless you are using integrated graphics) and that the monitor is powered on and set to the correct input. Check that the graphics card is fully seated in its PCI-e slot and that its power cables are connected.
- Overheating: Ensure all case fans and CPU cooler fans are spinning correctly. Verify that dust filters are clean and not obstructing airflow. Check thermal paste application on the CPU. Review your case's airflow configuration (refer to Figure 2.8).
- Component Not Detected: Re-seat the component (e.g., RAM, GPU, storage drive) and check its power and data connections.
- Unusual Noises: Identify the source of the noise. It could be a loose fan, a vibrating panel, or a hard drive. Ensure all components are securely mounted.
If problems persist, consult the specific troubleshooting guides for your individual PC components or seek professional assistance.
