Lots of folks are doing it, and practically all ITSP's are doing it.

If you're not sure how to secure the box, there are several well written
documents from various security groups to help you. In a nut shell,
disable all services that aren't needed, ssh term sessions only, and 
secure those services that you absolutely need. What's left running,
ensure those apps are up2date.
