Key Takeaway: Start with the five essential components (SD card, power supply, cooling, Ethernet, case). Add a UPS for any deployment where network uptime is important. Consider USB Ethernet adapter for advanced configurations. Optional components enhance convenience and capability but are not required for basic operation. Invest in quality components during initial setup rather than upgrading later.
