SBC recommendation for a small server?

[immutability]

In one post here I saw a "please buy hardware we recommend" quote, and I appreciate that, but I wasn't able to find a recommended boards list - is there even one? Or should I just use the standard/platinum support filtering on the main page?

 

Anyway, I could also use some help / recommendation for a general purpose SBC as I ... didn't by one for years. I'm looking for a more recent SBC to run a small, low power server (think pihole, homeassistant, zigbee, etc). I don't have specific requirements, but I'd like the board to have some kind of "long term support" and I'd also like to choose something that the armbian team would recommend, maybe from a manufacturer that supports armbian directly, or at least provides good documentation. Headless install, may use GPIO, at least 3 USB ports, built-in ethernet + wifi + BT (not sure if there's an SBC that would support zigbee natively?). And also, avoid using an SD card. Ability to use eMMC or SSD would be important.

 

Where I'm coming from: I still run two first-gen Raspberry Pis as webcams + dataloggers (the 26 pin GPIO ones with 256 and 512 MB RAM respectively) and I used OrangePi One and Lite as two surprisingly stable servers for years (one a small postfix mailserver + datalogger, the other even running 4 docker containers). I like using low-level hardware to its limits🙂 I have recently upgraded to an already outdated OrangePi PC+ that I found in the drawer - at least it has 1 GB of RAM and I was starting running into limits with the 512 MB ones. So yeah - I don't need the top of the range SBC but something ... reasonably priced (think ~40 €) that will run well for years to come. I heard good stuff about the Radxa boards with Rockchip SoCs but I have no experience as I haven't bought new SBCs in ... years. Thanks in advance 🙂
