Microsoft's transition from Windows 10 to Windows 11 rendered many PCs obsolete. However, these machines are proving suitable for home NAS systems. NAS systems run dedicated software like TrueNAS or Unraid, sidestepping Windows 11 requirements.
Hardware Compatibility
Retired Windows 10 PCs often meet NAS requirements. Essential hardware includes at least a 64-bit CPU, 8 GB of RAM (16 GB recommended), and adequate drive bays. Intel CPUs are advantageous due to Quick Sync for hardware transcoding.
- NAS uses do not require Windows 11 compatibility.
- TrueNAS recommends 8 GB RAM; 16 GB is optimal.
- Most 64-bit CPUs from the last decade suffice.
Form Factor and Networking
Mini-towers are ideal due to multiple drive bays and expandability. Network-wise, 1 Gb/s Ethernet suffices initially, with possible future upgrades.
Used PCs provide a low-cost NAS starting point but may lack airflow, drive bays, and upgrade paths. Consider future needs if the system evolves to a Docker host or VM server.
Considerations for Buyers
Before purchasing, verify the PC's RAM, drive bays, SATA ports, PCIe slots, and power supply. Planning specifications early prevents scope creep.
Retired Windows 10 PCs offer affordable, practical ways to start home storage projects or homelabs.
