A mini PC is one of the best Linux machines you can buy right now. It is standard x86-64 hardware, it boots from a USB stick, and most of the components are the same ones used in laptops — which means the drivers already exist.
That is the short answer. The longer one is that "runs Linux" hides three separate questions: will it boot, will the network and Wi-Fi work, and will it stay asleep or stay awake when you tell it to? Get those right and a $200 mini PC becomes a quieter, cheaper home server than almost anything else on the market.
Here is what to check before you buy, which distribution to pick, and how much memory each setup actually needs.
Key takeaways
- Mini PCs are standard x86-64 UEFI machines. Ubuntu, Debian, Proxmox and Home Assistant all install without special drivers on Intel-based models.
- Check three things first: Secure Boot (can it be disabled), the Wi-Fi chip (Intel is safest), and sleep support (S3 vs modern standby).
- A headless server OS uses 0.4–0.9 GB at idle versus about 4 GB for Windows. That is a free upgrade in usable memory.
- A typical six-service homelab stack needs about 6 GB. 8 GB is enough; 16 GB is for virtual machines.
- Containers beat VMs on memory: ten LXC containers cost less than one 2 GB VM.

Three things to check before you buy
1. Secure Boot. Almost every mini PC ships with Windows 11 and Secure Boot enabled. Linux installers handle this in one of two ways: Ubuntu and Fedora are signed and will boot with Secure Boot on, while Debian and Proxmox usually need it disabled in the BIOS first. Either is fine — just confirm the BIOS lets you turn it off, because some locked-down firmware does not.
2. The Wi-Fi and Bluetooth chip. This is the single most common compatibility problem. Intel AX201 and AX211 modules work out of the box with the in-kernel iwlwifi driver. Some Realtek modules need an out-of-tree driver and a kernel rebuild, which is exactly the kind of thing that makes a first Linux install miserable. If you plan to use Ethernet — and on a server you should — this stops mattering.
3. Sleep behaviour. Many modern mini PCs use "modern standby" (S0ix) instead of classic S3 sleep. Under Linux, S0ix support varies by platform, and a machine that will not suspend properly is annoying on a desk and irrelevant on a server that never sleeps. Check the BIOS for an S3 option, or plan to run it 24/7.
The good news: Ethernet, USB, NVMe storage, audio over HDMI, and Intel integrated graphics are effectively guaranteed to work. The 2.5 GbE Realtek controllers used on many mini PCs are supported by the in-kernel r8169 driver from kernel 5.x onward, which every current distribution ships.
Which distribution
Pick by what the machine is for, not by preference:
- Ubuntu Desktop or Linux Mint — if the mini PC is a normal computer. About 1.8 GB at idle, hardware acceleration works, and the install is the easiest of the lot.
- Ubuntu Server or Debian — if it is a server. 0.4 GB at idle leaves almost the entire machine for services. This is the right base for Docker.
- Proxmox VE — if you want to run several isolated systems. About 0.9 GB of overhead buys you a web interface, snapshots, and both containers and VMs.
- Home Assistant OS — if home automation is the only job. It is an appliance: you update it from the UI and never touch a terminal.
The practical point is in the chart: moving from Windows to a headless Linux install frees about 3.5 GB. On an 8 GB machine, that is the difference between "one service" and "four".
The homelab memory budget
People overestimate what a homelab needs. A Proxmox host running Home Assistant, Pi-hole, a Samba share, Jellyfin without transcoding, and three Docker containers lands at about 6 GB.
That means an 8 GB mini PC is a legitimate homelab server, not a compromise. It fits the stack above with 2 GB spare. What it does not fit is a Windows VM, a second Jellyfin transcode, or a local AI model alongside everything else.
The 16 GB tier is not for more containers — containers are cheap. It is for virtual machines, which reserve their memory up front, and for running a desktop session on the same box. The 24 GB tier is for people who want a Windows VM, several Linux VMs, and room to experiment.
Containers vs VMs
Proxmox gives you both, and the difference is not academic:
- LXC containers share the host kernel. Overhead is megabytes per container, and ten of them fit in well under 1 GB.
- Virtual machines run their own kernel and reserve their full allocation. Three 2 GB VMs cost 6 GB whether they use it or not.
Use containers for services that are Linux-native: Pi-hole, Home Assistant Container, Jellyfin, Samba, a reverse proxy, a download client. Use a VM when you need a different kernel or a non-Linux system: Home Assistant OS, Windows, TrueNAS, or anything you want to snapshot and roll back whole.
A practical default: Proxmox on the bare metal, one privileged LXC for Docker, one VM for Home Assistant OS, and containers for everything else. That setup fits comfortably in 8 GB and leaves you room to grow.
Home Assistant
Three ways to run it, and they are not equivalent:
- Home Assistant OS in a VM — the recommended path on Proxmox. You get supervised updates, add-ons, and snapshots through Proxmox. Costs about 2 GB.
- Home Assistant OS on bare metal — the simplest appliance. No Proxmox, no overhead, but the machine does nothing else.
- Home Assistant Container — lightest, about 0.5 GB, but no add-on store. You run each add-on as its own container.
For most people with a mini PC, option 1 is the right balance. The VM isolates Home Assistant from your other services, and Proxmox snapshots mean a bad update is a two-minute rollback rather than an evening of rebuilding.
Hardware transcoding
If you run Jellyfin or Plex, the integrated Intel GPU is the reason a mini PC beats a Raspberry Pi. Intel's Quick Sync block can transcode several 1080p streams in hardware at a fraction of the CPU load.
To enable it, you need three things: the intel-media-driver package (or i965-va-driver on older platforms), the container or VM to have access to /dev/dri, and hardware transcoding switched on in the media server's settings. Without the device passthrough, Jellyfin silently falls back to CPU and the machine runs hot for no reason.
For 4K transcoding, expect the CPU to matter more. A low-power N-series chip handles a couple of 1080p streams comfortably; multiple 4K transcodes are where a faster chip earns its price.
Power and sleep
This is the quiet benefit of Linux on a mini PC: the operating system stops doing things. No background indexing, no telemetry, no update checks at 2 a.m. A headless install typically idles a watt or two lower than the same machine running Windows, and it stays there.
Combined with the low idle draw of these platforms, a Linux mini PC running 24/7 costs roughly $9–19 a year in electricity at US average rates. If you are choosing a server machine, that is the number to compare, not the peak wattage. Our power consumption test has the full breakdown by platform.
Two settings worth changing on day one: disable sleep entirely if it is a server, and set the machine to power on automatically after a power loss in the BIOS.
Which BMAX fits
| What you are building | Pick | Why |
|---|---|---|
| Pi-hole, Home Assistant, a small NAS | B3 Pro — 8 GB, $199.99 | N-series silicon, around 6 W idle, dual HDMI. The cheapest sensible always-on server. |
| Proxmox with containers and a couple of services | B3 Turbo — 8 GB, $219.99 | Four cores instead of two, dual M.2 slots, still low power. |
| Proxmox with VMs, Docker, and a desktop when needed | B11 Pro — 16 GB, $459.99 | 16 GB is the point where VMs stop being a compromise; 2.5GbE for the NAS side. |
| Heavy VM host, local AI, or media transcoding at scale | B12 Power — 24 GB, $749.99 | 16 cores and 24 GB; also the model with a 2.5-inch bay for bulk storage. |
One caveat that applies to all of them: memory is soldered. You choose 8, 16 or 24 GB at checkout and live with it. For a homelab that means buying for the workload you expect in two years, not the one you have on day one.
Setup checklist
- Update the BIOS first, while Windows is still installed. Vendor update tools are Windows-only on most of these machines.
- Note the Wi-Fi and Ethernet chipsets before wiping the drive — lspci from a live USB is enough.
- Disable Secure Boot if you are installing Debian or Proxmox.
- Enable VT-x / AMD-V and IOMMU in the BIOS if you plan to use Proxmox or passthrough devices.
- Set the machine to power on after AC loss. A server that stays off after a brief outage is not a server.
- Use a static IP or DHCP reservation, and document it somewhere you will find it.
FAQ
Can a mini PC run Linux?
Yes. Mini PCs are standard x86-64 UEFI computers, and Ubuntu, Debian, Fedora, Proxmox and Home Assistant install on Intel-based models without special drivers. The main variable is the Wi-Fi chipset, not the platform.
Which Linux distribution is best for a mini PC server?
Debian or Ubuntu Server for a single-purpose box, Proxmox VE if you want containers and virtual machines, and Home Assistant OS if home automation is the only job. All three idle under 1 GB of memory.
Does Linux use less RAM than Windows?
Yes, substantially. A headless server install uses about 0.4–0.9 GB at idle against roughly 4 GB for Windows 11, which on an 8 GB machine is the difference between running one service and running four.
Can I run Proxmox on a mini PC?
Yes, provided the BIOS exposes VT-x or AMD-V. Proxmox itself needs under 1 GB, and its LXC containers add only megabytes each, so an 8 GB machine is a viable starter host.
Can I run Home Assistant on a mini PC?
Yes, in three ways: Home Assistant OS in a Proxmox VM (recommended), Home Assistant OS on bare metal, or the Home Assistant Container. The VM route keeps snapshots and add-ons while leaving the machine free for other services.
Will Wi-Fi work on Linux?
Usually. Intel AX201 and AX211 modules work out of the box; some Realtek modules need extra drivers. If the machine will be wired anyway, this is a non-issue.
Does hardware transcoding work for Jellyfin and Plex?
Yes on Intel integrated graphics, via Quick Sync and VA-API. You need the media driver installed and the container or VM given access to /dev/dri. Without that passthrough, transcoding falls back to the CPU.
Which BMAX mini PC is best for Linux?
The B3 Pro for a small always-on server, the B11 Pro for a Proxmox host running virtual machines, and the B12 Power if you also need local AI or heavier transcoding. All three are standard x86-64 hardware with Intel networking.
The bottom line
A mini PC is the least dramatic way to get a good Linux machine. No compatibility project, no driver hunt, no compromise on size or noise — just a small x86 box that boots from a USB stick and then disappears under the desk.
Check the Wi-Fi chip, decide whether you need Secure Boot, and pick the memory tier for the workload you expect in two years. Then install the smallest OS that does the job, because on these machines free RAM is the real upgrade.
8 GB, 6 W idle, $199.99. The BMAX B3 Pro is the cheapest sensible always-on Linux server in the range — and the quietest thing on your shelf.
