Pelican case (or comparable) that fits stock hardcase foam?

I'm wanting to upgrade to a harder, more secure case, but I'm happy with the foam in the stock case. I just wanted a harder shell. Does anybody know if any of the pelican cases are a good fit or close enough to fill the gap with some foam to make a snug fit?

I like some of the other hardcases I've seen, but I don't want anything bigger nor do I want to spend $300+.
