Should I encrypt servers at my home lab?

[whiteman808@paraboletancza.org]

Hey.

I've started building my home lab and currently I'm going to host stuff like nginx, jabber server, mail, git hosting.

The stuff I want to specially protect will likely be in e-mail and jabber conversations contents, and situations when someone is forgetting to encrypt them are not rare. I mean mostly received e-mails or friends who misconfigure their Jabber clients.

I want to protect against burglary and (most probable) against unwanted access to disk contents when I give my hardware to the service to repair it. I'm also doing torrenting (I personally don't like copyright law and support copyleft related movements) and want to protect also against seizing hardware by police (never happened in my home but not impossible).

Do you think that it's good idea to do full disk encryption on my server? Is remote unlocking server by supplying password through dropbear-based ssh in initramfs secure?

Thank you,
