Now this is mainly for my own purposes, as I doubt anyone else will want to build a Rat this way & I only plan on making one.  

Just a standard Rat, built on 0.15" vero and I've prioritised looks of build practicality (or at least what I think looks good anyway).  I have built this, and can confirm that it works

The layout probably makes more sense with a photo as a reference
