Opening a waveshare 2k screen

I bought this 9" 2k screen recently:

As I intend to use it for my synth, I want to extract the screen from the box - or at very least find a way to safely mount it and attach the cables inside the synth.

I contacted waveshare support, and while they said that they could not do this for me (not a problem) for such a low volume, they did send me some great pics of how to open the rear, which also means that I can possibly access and move the connector boards. I may not be able to fully remove the screen though, so I need to create some kind of bezel for it.

Oh, and I almost forgot - accessing the insides means I can connect wires to the on/off button to control it digitally.

Here is a cool ribbon cable based hdmi: https://www.aliexpress.com/item/1005002200767476.html?spm=a2g0o.productlist.0.0.726a3ff1r9Ggaf&aem_p4p_detail=2021071512223512888029912608890037608317
