Setup Steps

Step 1: Install the OS

The Beelink SER8 ships with Windows 11. You can keep Windows or install Ubuntu 22.04 LTS for a cleaner server setup. Ollama runs on both.

Step 2: Install Ollama

curl -fsSL https://ollama.com/install.sh | sh
ollama pull llama3.1:8b
ollama pull phi3:mini

Step 3: Install Open WebUI

docker run -d -p 3000:8080   --add-host=host.docker.internal:host-gateway   -v open-webui:/app/backend/data   --name open-webui   --restart always   ghcr.io/open-webui/open-webui:main

Step 4: Access from Any Device

Open WebUI will be available at http://YOUR_MINI_PC_IP:3000 from any device on your home network — phone, tablet, laptop.

FAQ

Do I need Docker? Yes for Open WebUI. Install Docker Desktop on Windows or docker.io on Linux.

Can this run 70B models? Not fully in VRAM. You can run them in CPU/RAM mode but expect very slow inference (1–2 t/s). For 70B, you need 64GB+ RAM or a dedicated GPU with 48GB VRAM.

What is the power consumption? The SER8 at idle draws ~8W. Under full LLM load, expect 30–45W — much less than a desktop GPU setup.
