Pretty much what the title says, I was wondering, since I want to invest on self hosting applications and my raspberry pi 3 b+ can barely function. I don’t have enormous expectations, just docker containers, nextcloud, pihosted, jellyfin… Any further suggestions (regarding the hardware) will be much appreciated.
depends on how many services you plan on running, i think the i3 would be sufficient for what you listed, the i5 would give you room to grow.
the i7’s usually aren’t worth it for servers since they are just a clock speed increase.
