I haven't actually started self-hosting anything yet, though at least I've bought a domain and I'm paying for an email service using that domain. It's nice and easy while still giving me some control my e-mail address and not being beholden to the likes of Google. I did so after my long time e-mail I had had all my life through my parents' internet provider was deleted with no warning.

I've also been looking into buying a NAS for use as a media server and backup target. I'll probably go with a Synology one for now, just to keep maintenance to a minimum. Maybe in the future I'll do something more advanced.
