Postie brought a few more bits for me today.
A three meter Anker USB-C cable, this will form part of the main harness that runs from the case to the remote controllers. Cheaper brands are available but as this is the one thing keeping me in touch with the CrystalSky, I didn’t want to skimp!
Five meters of 20mm braided sleeve. This stuff expands to about three times it’s size, I love it. I’ll be using this to wrap the three harness cables that will be running from the case to the controllers. It’ll keep it really tidy looking. I’ll also use a bit of this to sleeve the cables that run from the bottom of the case up in to the lid.
The all important aircraft switch 
I bought one with a red power LED in the tip too (12v).
What I hadn’t factored though, was the height of this mofo.
30mm from the mounting point to the top. I shall need to factor this in to the height I set the lower case plinth at to make sure the lid still shuts 
And a bunch of right-angled bracket things 
I’ll glue these to the inside of the lid, and the inside of the bottom of the case, in order to allow me to screw the final panels in to place.
