Use Cases:

• Smart home router (multiple device connections)

• Guest network isolation + ad blocking

2. OPNsense / pfSense

Why Choose It?
✅ AES-NI support: Can run IPsec VPN (~200Mbps throughput).
⚠️ Performance limit: Best for sub-500Mbps firewall rules or basic policy routing.

Use Cases:

• Small office firewall

• Home multi-WAN load balancing (dual 100Mbps broadband)

II. Lightweight Servers & Home Applications

3. Debian / Ubuntu Server (No GUI)

Why Choose It?
✅ Low overhead: CLI mode uses <300MB RAM.
✅ Docker-friendly: Can run Pi-hole, Nextcloud, Jellyfin (hardware decoding requires config).

Use Cases:

• Lightweight NAS (Samba/NFS)

• Local Git server or dev/test environment

4. Home Assistant OS

Why Choose It?
✅ Smart-home optimized: Supports Zigbee/Z-Wave USB devices.
✅ Smooth performance on N3160: Can handle 30-50 smart devices.

Performance Tip:

• Avoid running too many automation rules or camera analytics simultaneously.

III. Media Playback & Embedded Scenarios

5. LibreELEC (Kodi)

Why Choose It?
✅ Intel HD 400 GPU acceleration: Supports 1080p H.265/VP9 decoding, partial 4K support (testing needed).
✅ Extremely low power consumption, ideal for 24/7 operation.

Use Cases:

• Home HTPC (local media playback)

• Digital signage (info screens in stores/restaurants)

6. DietPi

Why Choose It?
✅ Highly optimized: Debian-based, pre-configured for lightweight services (Plex Server, WordPress).
✅ One-click installation for 100+ software packages.

Use Cases:
