What is the difference between the Habro cases and the one you have Storm Shadow? That, and how much do you want for your old ones?
The Hasbro cases have a few benefits:
#1) They aren't as deep as the star cases I have so I find you see the figure better and there's a lot less wasted space. The star case is almost twice as deep as it needs to be for a G.I. joe figure. Other then that the star case fits perfectly and works pretty well. I just needed the space.
#2) The Hasbro case adds a couple of nice touches with G.I. Joe stamped on the back cover as well as a Cobra symbol up top. If you have a Mail-In Doc figure the case is just about the same, but a little deeper.
I can take pictures tonight when I get home.
