What's the point of this? Where does it fit, who is it aimed at apart from Explaining Computers and good old Jeff Geerling (hiya Jeff!). Maybe if it has been designed into a retro style case or something? As it stands it's very hard to see who would want this.
Certainly something which could grow to support some Arduino work.
EDIT: Admittedly this would be a no brainer if there was an off-the-shelf Atari ST style thing - https://en.wikipedia.org/wiki/Atari_ST purely for the sheer mass providing some protection.
