Metal Case assembly help

I have a Shruthi built and am trying to put it into the Hallik Engineering metal case, but have absolutely no clue what to do with the various washers, nuts and standoffs. What is the proper order for assembly? I’ve put together several acrylic cases, but this is definitely different.

Maybe this old post from Adrian will help?
