I am looking to self host my own media server (Jellyfin), a personal page and something more in the future and I need to choose my server hardware. I have decided on buying a single board computer to save on energy, space and, perhaps, cost.

Jellyfin docs recommend a computer with a Rockchip RK3588 / RK3588S processor. I would also need ethernet, USB for external storage, at least 4GB of RAM and maybe a M.2 slot for the OS and more space.

I know about Armsom and OrangePi, are they any good?

My budget would be up to 150 euros and I live in the Netherlands. Any suggestions?
