Unfortunately, the Mini is not designed to be stackable. It would have been so easy for Apple to have done this, but they didn't. So no matter what the pictures look like, you will never get these third-party items to seamlessly sit beneath the Mini.

Now if someone came up with a complete chassis replacement that included extra hardware, ports, etc., that would be interesting.

I just don't like the idea of taking something designed to be small and elegant and make it bigger by adding onto it. I'd much rather have an external HD separate and a UBS and FireWire Hub hidden off somewhere rather than have it all under the mini. Besides, my mini fits perfectly under my 20" ACD, making it taller it wouldn't fit anymore.
