Hi, I have a small suggestion: please use quality screws.
I got the IMK Corne as my first GB case, which I thought was quite expensive for what it is, and was super disappointed to see that they cheaped out on the screws. It was not even mid range screws, but low end pot metal chinese crap.
Proper m2 screws specced for industrial use might cost you ten cents a piece (that's roughly what I pay when I buy for the factory where I work @ 1000 qty boxes), but they will give a real quality feel when assembling, will last a lifetime and will not wear the threads of the case as much.
Might be overkill, might be insignificant, but I think it'd be a shame not to use proper fasteners considering the solid looks of the case!
