Best Mini PCs for pfSense and OPNsense on AliExpress
Build a pro-grade home firewall with an AliExpress mini PC — pfSense and OPNsense on N100 hardware starting at $130.
AliExpress mini PCs with dual Ethernet ports are the go-to hardware for pfSense and OPNsense firewall builds. The Intel N100 processor offers the best performance-per-watt for router applications.
What to Look For
Key factors to consider before buying on AliExpress
🔌
Ethernet Ports Are Critical
Dual 2.5Gb Ethernet is the minimum for a pfSense build. Intel i226-V NICs are preferred for driver support. Realtek 8125 NICs work but need driver installation on FreeBSD.
🧠
CPU Performance for Routing
N100 handles 1Gb routing with ease and can handle 2.5Gb with IDS/IPS. Higher-end N305 or Core i3 for VPN throughput (WireGuard) at multi-gigabit speeds.
🔋
Power Efficiency & Cooling
N100 mini PCs draw 6-10W at idle, 15-25W under load — excellent for 24/7 operation. Active cooling is preferred for sustained routing workloads.
