Actually, what I did was cut out the basic shape for the empeg. Then laid the block of foam on the table next to the empeg. The distance from the top of the empeg to the top of the foam block was exactly the amount I trimmed from the bottom of the foam. I just used a large kitchen knife, and it cut through the foam like butter. You can’t just pluck the bottom layer off, because the cubes are long and tall. They are not actually cubes, but long pillars if you can imagine. Then I used the same knife (razor sharp) to cut small areas out for the RCA jacks and docking plug in the back. Also, 2 small slots for the screen as you can see in my pics.

Hope that helps. Basically, if you want to fit cables and stuff, get the 1400, but if you want only the empeg to fit, get the 1200. They are great cases!
