If you want it easy, you can buy something like a Synology NAS where you can install locally hosted Email, Contacts, Calendar, Dropbox and Photos servers with a few clicks. The software is of decent quality as well.
Obviously you pay for the convenience, but it's not a lot for self-hosted and maintained stack at home.

Contacts are, unfortunately, still under Google. Just under a separate email.
Important email is hosted through https://soverin.net with a custom domain.
Never used Calendar and have no plans to.
This is really commendable. Do you host your own E-mail/Calendar/Contacts server? if so, what's your setup like in terms of hardware and the software stack?
