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

  1. Verify all power cables are connected.
  2. Confirm fan orientation and connection to appropriate headers.
  3. Ensure RAM, GPU, and cooler are firmly seated.
  4. Check nothing obstructs ventilation or fans.
  5. Remove all screws/tools from inside case.
  6. Install side panels, case on desk, and attach monitor/KB/mouse.
  7. 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.
