Beelink mini PC runs Proxmox VE for $349

Javier Barbaran built a home server on a Beelink S12 Pro mini PC, installing Proxmox VE to run multiple isolated services [Dev.to]. The hardware stack consists of a Beelink S12 Pro with an Intel N100 (2 GHz base, 3.4 GHz boost), 16 GB DDR4 RAM, a 512 GB NVMe SSD, and a 12 V/1.5 A power supply that draws roughly 15 W at idle [Javier Barbaran].

Proxmox VE 8.2 was installed from the official ISO via Balena Etcher on a USB stick. The installer prompts for disk selection, network config, node name, and root password, and completes in ten minutes [Dev.to]. After reboot, the web UI is reachable at https://<IP>:8006.

Barbaran's configuration uses LXC containers for lightweight services (Alpine-based AdGuard DNS, Tailscale VPN, n8n workflow engine) and a single VM (Ubuntu 22.04) for Home Assistant, which requires full kernel isolation [Javier Barbaran]. A central PostgreSQL instance runs in its own container, serving all other services.

The Beelink S12 Pro draws less than a typical desktop (≈80 W) while still delivering enough CPU cycles for modest web services and small AI models on the N100 [Dev.to]. This setup provides a production-grade hypervisor, allowing users to experiment with virtualization, networking, and storage concepts that would otherwise require expensive enterprise hardware [Javier Barbaran].
