Best Mini PC for Docker in 2026: 4 Practical Picks

For a small first Docker host, use the under-$500 configuration guide to budget the complete machine and required storage.

A mini PC running Docker is the simplest path to self-hosting: no hypervisor to configure, no NAS vendor lock-in, and no rack to fill. Install Ubuntu or Debian, run docker compose up, and you have a home lab.

Not every mini PC suits 24/7 container work equally well. Memory ceiling, storage layout, networking, and the specific services you run matter more than any generic container count. The four picks above and one unlinked alternative cover distinct trade-offs, based on each manufacturer’s published specifications or, for the S13, the Amazon listing sold by Beelink.

What matters for a Docker mini PC

Memory is the hard ceiling. Every running container uses memory, and the heavy ones (databases, media servers, and machine-learning workers) use far more than a reverse proxy or DNS filter. Add up what your services need and leave headroom. If the memory is soldered, as on the SER9 Pro, that ceiling is permanent.

Storage layout matters for volumes. Docker volumes live on local disk. NVMe drives offer much more throughput and lower latency than SATA, which helps databases and photo libraries such as Immich. A second drive lets you keep volumes off the OS drive. The SER9 Pro, UM890 Pro, EQ14, and S13 have two M.2 slots (the S13’s second slot runs at PCIe 3.0 x1), and the G3 Plus has an extra M.2 2242 SATA slot.

Power draw determines running cost. A Docker host runs around the clock. At $0.18 per kWh, each watt of continuous draw costs about $1.58 a year, so a system averaging 10W costs about $16 a year. Measure your configured system at the wall rather than relying on processor ratings.

Networking matters for transfers and separation. Gigabit Ethernet handles several media streams and everyday service traffic. 2.5GbE helps with large file transfers and backups to a NAS. Two ports let you separate container traffic from management, but that separation still takes deliberate network configuration.

Our pick: Beelink SER9 Pro

The Beelink SER9 Pro is the Docker host we recommend if you’re starting fresh. Its Ryzen 7 H 255 has eight Zen 4 cores and 16 threads, which means fast concurrent image builds and headroom for CPU-heavy services such as Immich’s machine-learning worker or a self-hosted CI runner.

It ships with 24 or 32 GB of LPDDR5X-6400 and a 1 TB PCIe 4.0 SSD. The second M.2 2280 PCIe 4.0 slot lets you add a dedicated volume drive, which we recommend for anyone running databases or media indexers.

The main limitation is soldered memory. Choose the 32 GB configuration, because you can’t upgrade later. If you expect to need 64 GB or more, the Minisforum UM890 Pro has socketed DDR5.

The 2.5GbE port handles NAS traffic and backups, and USB4 adds a fast path for external NVMe enclosures.

Best value: Beelink Mini S13

The Beelink Mini S13 is the entry point for Docker self-hosting. Its Intel N150 is a 4-core, 4-thread processor with a 6W base power rating, suited to services such as Portainer, Nginx Proxy Manager, Pi-hole, Vaultwarden, and Home Assistant.

It comes with 16 GB of DDR4 on one SO-DIMM and a 500 GB SATA SSD, and a second M.2 slot takes an NVMe drive at PCIe 3.0 x1, so you can add a drive for volumes or backups. It’s not the machine for PostgreSQL, Immich, and Jellyfin together, but it makes a good dedicated host for a set of lightweight services or a secondary node.

Its two 2.5GbE ports let you give containers their own network and keep management separate, the same layout as the EQ14. Beelink’s own store doesn’t list the S13, so these specifications come from the Amazon listing sold by Beelink.

Also consider: GMKtec NucBox G3 Plus

The GMKtec NucBox G3 Plus is an N150 host with an NVMe boot drive, a separate M.2 2242 SATA slot, and one 2.5GbE port on an Intel i226-V controller. GMKtec lists a single DDR4 SO-DIMM slot that takes up to 32 GB, although Intel’s specification for the N150 lists 16 GB.

We don’t link it because we couldn’t verify a retail listing for this exact model: searches return other GMKtec machines (G3S, G3 Pro, G10, G11) with different processors, and GMKtec’s own store showed the N150 G3 Plus sold out. If you find one, confirm the listing names the N150 G3 Plus. For more budget options, see our N100/N150 roundup.

Performance pick: Minisforum UM890 Pro

The Minisforum UM890 Pro is for Docker users who know they’ll outgrow 32 GB. Its Ryzen 9 8945HS has eight cores and 16 threads, and its two DDR5-5600 SO-DIMM slots take up to 96 GB, enough for a mixed Docker-plus-VM setup under Proxmox.

The dual 2.5GbE ports are a real advantage for Docker networking. Assign one to a macvlan network for containers that need their own LAN addresses, and keep the other for SSH and management.

Its Radeon 780M supports hardware transcoding in Jellyfin through VA-API. Plex’s Linux hardware transcoding supports Intel Quick Sync and NVIDIA, so choose an Intel pick if Plex is part of your stack.

Step up: Beelink EQ14

The Beelink EQ14 is the step up from the S13, for about $20 to $40 more. It uses the same N150 and, on the reviewed version, has the same two 2.5GbE ports, on Intel i226-V controllers. Beelink also sells a dual-gigabit version under the same name, so check the listing. What it adds is two M.2 2280 PCIe 3.0 slots for NVMe drives, where the S13 pairs its SATA SSD with a single PCIe 3.0 x1 slot, plus a second HDMI port and a built-in power supply.

On either machine, the second port lets you put containers on their own network segment and keep management separate, provided your switch and router are configured for it. If you want a firewall on the same hardware, run OPNsense or pfSense in a VM under Proxmox or on bare metal. They are complete operating systems, not Docker images.

The two M.2 slots let you keep the OS and Docker volumes on separate drives. Beelink lists a SATA SSD in the base configuration, so add an NVMe drive in the second slot if volume performance matters. Memory is one DDR4 SO-DIMM with a 16 GB maximum.

Storage strategy for Docker volumes

Whichever mini PC you choose, how you handle Docker storage matters.

Separate OS and volume drives. If your mini PC has a second drive position, install the OS on one drive and keep Docker volumes on the other. A named volume that points at the second drive looks like this in docker-compose.yml:

volumes:
  app_data:
    driver: local
    driver_opts:
      type: none
      o: bind
      device: /mnt/nvme1/docker/app_data

Use bind mounts for simpler backups. Bind mounts are easy to back up with rsync. Named volumes need docker volume commands or a helper container to export, which adds steps to your backup scripts.

Monitor disk usage. Images, build cache, and logs accumulate quietly. Run docker system df regularly, and prune unused images and build cache on a schedule that suits your stack.

Network configuration tips

On a single-NIC mini PC, Docker’s macvlan driver can give containers their own IP addresses on your LAN:

docker network create -d macvlan \
  --subnet=192.168.1.0/24 \
  --gateway=192.168.1.1 \
  -o parent=eth0 \
  docker_lan

Replace eth0 with your interface name, such as enp1s0, and use your own subnet and gateway. Docker’s documentation notes two caveats. Containers on a macvlan network can’t talk to the host directly, and your network equipment must allow one port to use multiple MAC addresses (promiscuous mode).

On dual-NIC machines such as the S13, EQ14, and UM890 Pro, you can dedicate one interface to Docker and the other to host management, so a misbehaving container can’t lock you out of SSH.

How to choose

How much memory will your services need? For a reverse proxy, DNS, monitoring, and a few small apps, an N150 box such as the S13 or EQ14 is enough. For databases, media apps, or machine-learning workers, choose 32 GB with the SER9 Pro, or the UM890 Pro if you want room to grow. For Docker alongside several VMs under Proxmox, the UM890 Pro’s 96 GB ceiling gives you the most headroom here.

Do you need network separation? For a separate IoT network, a firewall VM, or management on its own interface, a second port helps. That points to the S13, the EQ14 (in its dual 2.5GbE version), or the UM890 Pro. Single-port machines can do the same with VLANs and a managed switch, with more configuration.

If you’re new to Docker, start with the S13 or another box from our N100/N150 roundup. When you outgrow it, the small box can become a dedicated DNS or monitoring node.

The bottom line

For most home lab users, the Beelink SER9 Pro is the right Docker host. It has eight Zen 4 cores, 24 or 32 GB of memory, and two M.2 slots. Buy the 32 GB version.

For a low-cost start, the Beelink Mini S13 handles lightweight services with dual 2.5GbE, and the Beelink EQ14 steps up to two M.2 PCIe 3.0 slots and a built-in power supply. The GMKtec NucBox G3 Plus is an unlinked alternative if you can find the exact N150 model. If you need maximum memory headroom, the Minisforum UM890 Pro scales to 96 GB.

Pair any of these with a NAS for bulk storage for a clean separation of compute and data.
