he/him
My home server is a RockPro64. I didn’t specifically buy it for that purpose but since I had it lying around I figured I might as well use it.
It has a PCIe Slot which I used for a SATA controller, with two 3,5" HDDs.
They have an official NAS case for it too, not sure I’d recommend it as it’s kind of expensive, doesn’t isolate HDD vibration / noise at all and isn’t very convenient to service (to replace the drives for instance). I’m not aware of a better case option for this board though.
I run debian and OpenMediaVault on it (I didn’t have to mess with the kernel or device tree at all), with the ZFS plugin, and several docker containers (Jellyfin, PiHole, Syncthing, Tailscale).
For my needs it’s working perfectly fine and doesn’t need much power. But:
TL;DR these low power ARM boards are just fine as a cheap option for getting into homelab / Self hosting and I wouldn’t necessarily recommend against them, but sooner or later I want to build a low power x86 based NAS with more RAM, SSD cache and TrueNAS Scale instead.
I’m not aware of another one. Some other distros like Ubuntu and OpenSUSE ship AppArmor instead, which does similar things but isn’t considered quite as secure.
I know plenty of other popular distros don’t ship any Mandatory Access Control system at all which seems like a very bad security practice to me. Same thing with Firewalls.
