Since you have no control over it (aside from ripping it out of the wall), you're at the mercy of whoever runs the box to adequately secure it. When it gets hacked, any shady business conducted by the miscreants will be emitted from /your/ IP, so you're exposing yourself to TOR exit node level liability. You might be able to work around that.... but it depends what's running on the box. If it's a backend server for some organisation (database, etc) then you could have some sort of tunnelling router between it and the fibre that routes all packets back to the organisation's datacentre.
