Best Mini PCs For Homelabs, Home Assistant, And A Real Home Router

I love mini PCs because they let you do real homelab stuff without pretending your spare room is a data center.

That is the whole appeal for me. I want small, quiet, low-power boxes that I can leave running all the time without feeling ridiculous about the electric bill or the noise. And honestly, modern mini PCs are way more capable than most people expect.

The only real trap is buying the wrong kind. A lot of these boxes look similar on paper, but they are not all good at the same jobs.

The three mini PC lanes I keep coming back to

The cheap always-on box

This is the N100 or N150 kind of machine. For Home Assistant, Pi-hole, Docker, Tailscale, a little media automation, or some basic server stuff, these things are insanely good for the money.

They are not sexy. That is part of why I like them. They just sit there and do the job.

The router box

If the mini PC is going to become your router, I care way more about the ports than the CPU flexing.

Give me dual 2.5GbE, solid thermals, and a reputation for not being weird. That is more important than buying some overpowered box with the wrong I/O and convincing yourself it was a smart decision.

The one-box-does-a-lot machine

This is for the people who know the little server is going to grow legs. Maybe it starts as Home Assistant and a couple containers. Then suddenly it is Plex, backups, a few VMs, Frigate, and six experiments you swore would be temporary.

That is when I want more RAM headroom, better storage options, and a little breathing room.

What I look for before I buy

dual 2.5GbE if router duty is even a possibility
NVMe storage that is actually replaceable
cooling that is quiet enough to live with
a brand people have at least heard of
power input and ports that do not feel weirdly proprietary

I also strongly prefer boxes that look normal. If it looks like a fake gaming accessory from 2013, I am already annoyed.

How I would choose one without overthinking it

If this is your first homelab box, I would start cheap. Seriously. A small N100 system is enough for a shocking amount of useful stuff.

If the box is touching your internet connection directly, I would prioritize the NICs and the thermals before anything else.

If this thing is about to become the brain of the house, I would spend a bit more for RAM headroom and better storage instead of chasing the absolute lowest price.

RAM and storage, the part people cheap out on

8GB is okay for tiny single-purpose stuff.

16GB is where these machines start feeling comfortable.

32GB is where they stop feeling like a toy and start feeling genuinely flexible.

For storage, I want NVMe pretty much every time. These little systems feel so much better when the storage is not dragging everything down.

What I would personally buy

For a clean little Home Assistant or Docker box, I would buy an N100 mini PC with 8GB or 16GB and move on with my life.

For router duty, I would buy around the ports first: dual 2.5GbE, stable cooling, one NVMe slot minimum.

For the “I know this one box is going to end up doing too much” setup, I would buy the version with more RAM support and better expansion before I regret it later.

Final thoughts

For most people, a good mini PC is the correct homelab answer. Not a rack server. Not some giant old enterprise box you got for cheap and now have to emotionally justify. Just a nice little computer that sips power and does useful stuff all day.

Buy for the role, not the benchmark screenshots, and these things are hard to beat.
