I’ve had several ARM-based mini PCs in my online shopping cart for the past few months. What really caught my attention was the passively cooled chassis and low idle power, suitable for my home lab experiments. Also, the price tag seems good enough not to hurt the wallet.
Apple’s Apple Silicon-powered Mac mini has already proven that Arm chips can punch well above their weight class. Devices based on newer Snapdragon X series targets the premium bracket, while Rockchip’s RK3588 is more niche affordable SBC and mini PC level. Those per-watt performance numbers are hard to ignore.
The mini PC area started to record. A small, always-on box behind the monitor to manage a handful of self-managed services was all I wanted. That’s what motivated me to pull the trigger. But after researching if it would actually work in my home lab, I took a step back.
The OS options are narrower than I expected
Arm mini computers check a lot of boxes on paper
as x86 minicomputer ownerI took a few things for granted. Most importantly, I can throw any OS at it and it just works. From Proxmox to Ubuntu Server, or even Windows 11. The Mini PC runs everything on x86 hardware. This flexibility is because the x86 mini PC is part of my home lab. As your needs change, you can always repurpose the box without worrying about whether the hardware underneath can support your favorite OS.
ARM minicomputers don’t have the same freedom. Many of them ship with Linux or Android customized by the vendor. These customized operating systems are closely related to the System-on-Chip hardware. So you will struggle with the lack of proper kernel support, and sometimes it’s non-existent.
I was planning to run a community-supported OS, but that requires custom kernels, patches, and device trees that may or may not be maintainable. Unfortunately, Proxmox does not officially support ARM. The forum thread covered the partial workaround mentioned a few months ago.
This means that my always-on home lab box will be dependent on a stranger’s GitHub repo. It’s not exactly a solid foundation for something I want to build, then forget about for months.
More than half of the containers do not have an ARM build
Docker is where things really get done
Docker was where the compatibility issues first appeared. I reviewed the Docker Hub pages for services such as a media server, a reverse proxy manager, and several monitoring tools. Then I found out that the Arm64 scope is inconsistent across the board.
I found a lot of architecture images, but a few had Arm64 tags that were months after the main release. These community-maintained tags had several open error threads. The last Arm64 build for a container I rely on every day was over a year old.
on a Mac, Rosetta 2 It handles the x86-to-Arm translation quietly in the background. Linux has no analogues. Allows you to take Docker x86 images and run them through QEMU emulation. But this is not a pure experience. You’ll experience slowdowns, unexpected crashes, and useless debugging sessions. You’ll be chasing an emulation quirk rather than an actual problem with your setup.
A few tools I use don’t have containers that support the ARM platform – CLI utilities, sync clients, and a few home server apps that only work with x86_64 binaries.
If the app doesn’t ship an Arm build, if the project is open, compiling from source is technically an option – but it’s too much overhead for the tools I just want to run. This is not a problem for popular projects, as they tend to support many architectures. So the unavailability continues niche self-hosted apps which does not support ARM.
Who do ARM mini PCs actually work for?
Not a bad platform, just not for my use case
For a clean and Arm-native home server workload, these mini PCs are really attractive in terms of hardware. If you plan to run, a light NAS, Pi-holeand other utilities, the ARM mini PC’s power efficiency and low noise profile make a lot of sense. Qualcomm’s latest chips in particular deliver impressive results. The trajectory of the ARM ecosystem on Linux is clearly headed in the right direction.
But my stack is the opposite of purposeful. It is a set of containers and tools that solve the problem at that time. This is where armun ecosystem gaps do the most damage. For an affordable home lab, this friction adds up quickly.
Friction disappeared with the x86 mini PC
I got an x86 mini PC instead. Moment N100 based box It idles at about 5-8W, which is competitive with most ARM devices I’ve reviewed. Proxmox installed on x86 mini PC without problems. Every container I shot ran as a native image and started on the first try. No workaround or emulation was needed.
The ARM ecosystem on Linux is maturing. I’d revisit it in a year or two, especially if the projects I use in my home lab get a lot of architectural support. Right now, if you’re planning to run a real home lab workload rather than a dedicated service, the ARM mini PC is still a long way off. You’re better off with an x86 architecture that handles everything and gets out of your way. Sometimes that’s all you need to set up a home lab.
