Installation Best Practices

Initial Installation

1. Prepare the case: Remove protective films, verify all pieces present
2. Install board: Place board in case carefully, avoiding static discharge
3. Secure mounting: Use provided fasteners, ensure firm attachment
4. Cable routing: Plan cable paths before assembly
5. Final assembly: Close case and verify all panels fit properly

Thermal Considerations

• Ensure heatsink or cooler fits within case envelope
• Maintain airflow paths if case has ventilation
• Do not block cooling solutions with case walls
• Test temperature after installation to verify adequate cooling

Cable Management

• Use cable ties or clips for organization
• Avoid sharp bends or kinks in cables
• Keep cables away from moving parts (fans)
• Plan cable exits before assembly

Troubleshooting Case Issues

Common Problems

Overheating with case installed:

• Verify ventilation not blocked
• Check thermal solution installation
• Ensure fan operation (if applicable)
• Consider adding ventilation holes

Poor fit or misalignment:

• Verify correct case for your platform
• Check for manufacturing defects
• Ensure board installed correctly
• May require padding or shims

Difficult access for maintenance:

• Plan access before final assembly
• Consider removable panels for frequent access
• Mark areas needing frequent attention
• Modify case if necessary
