Here are some quick pictures. The names are pretty much self-explanatory, but if you have any questions, fire away. I wasn't able to locate the carrying strap I made from the Micro Spider handle, but one of the pictures shows the hook & loop connection on the side of the Amplifi 30. If I find the strap, I'll show what it looks like attached to the amp.
Edit: I see that the filenames don't show up. So here's a brief description.
Picture 1 -- Amplifi 30 inverted and snugly fitting in the case, with power supply and cables at the bottom of the cooler. If you're not comfortable with the snug fit, the blue hard plastic liner comes out, which will make for a looser fit, but also result in less protection from impacts. The liner is slightly tapered, so the amp will not go all the way to the bottom, which leaves some storage space for accessories below.
Exterior view, showing Velcro closure strap and external pocked, good for cables, capo, etc.
Bottom storage area.
This tray is designed to fit at the top, to separate what you put up there from the contents on the bottom. (Nominally, beer or soda cans...) I've inverted it so that it fits nicely around the amp's perimeter and keeps it centered in the blue plastic shell.
The 2" heavy duty hook & loop connection for securing the carrying strap/handle. (not shown)
