Jim .... it IS smaller than the s900, but slightly larger than the 3k. Th issue was not the width, but the length ..... it's a smidgen longer and that was just enough to make it too large for the corners of my old case.

I bought a GSK6 from: www.gigskinz.com

Fit's like a glove, and I'm happy again !
My stand setup was 99% the same. I just have to tweak a few things to get the best viewing angle for my screen.

This case is perfect.
I'm all set up and ready to go!
