The security of the system as far as it walking off isn't that big of a problem. I was mainly concerned about people just messing with it. The janitorial staff has been known to have problems in the past.
I think it would just be cool to have it in my desk, away from sight. And I could use the extra room on top of my desk that it would give me. The shuttle is too expensive, but I just found out that the case I linked to earlier will fit with 1/4" to spare. And it's only $30
