Introduction
Clean cable management ensures good airflow, quiet operation, and easier future upgrades.
Cable Management Tips
- Route cables behind the motherboard tray, using cable ties and grommets.
- Bundle related cables (SATA, front panel) using Velcro straps.
- Avoid sharp bends—maintain gentle curves for airflow and aesthetics.
Final Pre-Boot Checklist
- Verify all power cables are connected.
- Confirm fan orientation and connection to appropriate headers.
- Ensure RAM, GPU, and cooler are firmly seated.
- Check nothing obstructs ventilation or fans.
- Remove all screws/tools from inside case.
- Install side panels, case on desk, and attach monitor/KB/mouse.
- Power on and enter BIOS to check system health.
Troubleshooting Before Boot
- No POST or beeps: Recheck PSU and front panel cables.
- High idle temps: Re-seat cooler or apply thermal paste.
- Fans spinning abnormally loud or slow: Verify BIOS fan curve settings.
