You will need to sand the OLED header down so that the plastic is about 7mm in height (not including the pins). Also remove any plastic spacers on the OLED pins, and make sure the pins insert fully into the now shorter header. If it doesn't sit flush with the OLED PCB, cut the OLED pins a bit shorter until it does.
It is also possible to replace the Elite-C with a nice!nano for wireless support or a Pro-Micro since the bottom 5 pins are not used. But the included case design expects the controler to be soldered directly onto the PCB, so using a controller that requires low-profile sockets (I suggest Mill-Max 315-43-112-41-003000) will also require a change to the case to allow for the extra height. Try cutting out a space below the controller on layer #8 (similar to layer #7)

Questions
How big is the Dissatisfaction30 PCB?
It measures 190.5 × 85.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dissatisfaction30 use?
55 parts, built around the BAV70. 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 Dissatisfaction30 KiCad files?
From the dcpedit/dissatisfaction30 repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic bottom/bottom.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dissatisfaction30 design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
