good alternatives to raspberry pi which are cheap and efficient?

Hello , dear lemmy users , I am starting to really like self-host because they are really fast and mostly i use open source stuff (like lemmy /photon etc) which were sometimes slow but after self hosting it now on the pc i am on using , i really like it

Now , I would like to host some stuff like jellyfin , navindrome , photon , adgaurd home and just leave it running on a device in maybe near future (i can convince my brother to pay for it , after he gets his job maybe)

TLDR : I wanted to ask What's your favourite alternative to raspberry pi for simple self hosting or maybe possible near home automation

Edit: thank you all for helping me , I am starting to believe that i should look into using dell wyse or the likes which are meant to be used for hosting or a old laptop (since i dont own a laptop anyway , i just own a pc ) and since i run linux anyways , i am thinking of owning a laptop dual booting it with alpine (that has docker) and a simple minimalist os like hyprland on it just in case i need to travel with it (which to me seems very unlikely , I dont travel much so..) I am confused about it

Edit 2 : I am very new to self hosting so currently i would run stuff on my pc only (using portainer) , However when needed to buy , i am thinking of buying the cheapest thin client maybe a nuc or dell wyse

I am already trying searxng , shiori(bookmark manager) , portainer,freshrss , photon , froodle-s pdf tool which i have all closed except portainer currently I am also thinking of shifting to podman as well but cant find a good gui for it like portainer , (portainer really just blew my mind with its templates)
