Essentially, what I'm looking for is thus:

- someone breaks into my always-locked equipment room
- someone steals the box(es) in question, which obviously means shutting
down the unit

I don't want said thief to be able to retrieve the data after the box is
stolen, which is why I'd like a passphrase, and a removable key. Even if
the passphrase is captured, the data will still be protected because I
have the only key to the system 35 miles away on my person.

There is no possible way this would go unnoticed. Anyone that could gain
access to the already secured room would have a window of about 15
seconds to break into the building after hours (secured/alarmed), smash
in the secured equipment room door, grab the box (out of about 40) and run.

Like I said, it won't go undetected. The equipment is in a very secure
equipment area, inside of a secured and alarmed building. All equipment
is monitored 24/7, so if the box was physically altered, I would be
alerted via SMS/email immediately.

> An important point that too many people forget.

I agree, but this is not the case here. I just want the data protected
if the box goes down, whether by physical intruder, or I force it down
myself.
