USB outlets in the back?

Many times when I talk about USB technologies, specifically flash drives, I'm asked about "our older computers which only have USB outlets in the back". Short of upgrading or installing an internal hub in an empty bay, the simplest solution is to run a USB extension cable from the back of the computer up to the desk. But then how to secure them. Well, at the lab I was in at the North Platte Community College they've come up with a solution: attach the user's end of the cable to the monitor. You can see how they've done it in the two photos below.  (The cable ties are easy to find. If anyone can supply a link to somewhere that sells the part stuck to the monitor I'd appreciate it.)
