Features
-128x32 OLED Display -16 Keyswitches
Note
I am also requesting a grant for a soldering iron (obviously with solder) for this project from Hack Club.
Cad Model
I used heatset inserts and M3x16mm screws for the case.
It has a simple Top and Bottom. The PCB sits in the middle.
This image displays the full model with the PCB inside.
Made in Fusion360.

Questions
How big is the KiCad Work PCB?
It measures 113.9 × 111.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KiCad Work use?
34 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the KiCad Work KiCad files?
From the kaleb973/MiniMac repository on GitHub, at the commit this page was made from: the board is PCB/KiCad Work.kicad_pcb and its schematic PCB/KiCad Work.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KiCad Work design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
