it’s just me that’s going to be using whatever it is, i plan to host a Nextcloud, probably a Matrix server using Synapse, a website, and email. i have an Ethernet cable ready to go, but i’m using someone else’s internet at the moment (with their knowledge and approval).
i’ve been looking at Pine64 SBCs, but i’m open to anything as long as it’s not a Raspberry Pi
For the most part, yes. Some things, like SIEMs, IDPSs, machine learning (GPT, Stable Diffusion, etc.), and other such processing-heavy things should be taken into consideration and “fed” properly.
