What I would do is take the measurements for the case you want, do a tape outline or cut a piece of paper to those dimensions, and then see how you can arrange them to see if they fit. Other than that, the only thing you could do is get the case and see. Just remember you want an inch or better between the outside of the case and what you put in it, and some seperation between the contents too.

And no, you're not going nuts. I had a problem with the post, and was probably fixing it while you were typing yours.

OK, if you ARE going nuts, it wasn't from that....
