hello all, Im looking to host a server on a raspberry pi but I am unsure which pi to purchase. I am assuming I need a certain level of specs/ memory for it to work properly but I cant find any info on mastodons webpage…

The server would be for social interaction and document storage- is storage the only thing I would be concerned with. If so I’m assuming I can purchase additional storage as I go…?

I’m a complete server and mastodon noob only knowing they can be set up in a house as my brother used to host many (He is currently very ill or I would ask him)

Thanks so much!
