Khador Behemoth Kit - What's inside the plastic/resin kit?

When I picked up my Khador Behemoth I was curious what the difference was between the prior all metal version and the current resin and metal kit.  I couldn't find much on the Internet as far as pictures, so when I opened up the kit I decided to take some video so others that wanted to see what was inside would have some reference material.

I did end up painting the Behemoth, after mounting on a Protectorate of Menoth Wreck Marker.  You can see pictures here.
