Hello, I could go into detail of how I started. But ultimately after hundreds of dollars, in my lifetime of the "best keyboard" quest.
I have several Realforce RGB Topre boards. Through some online research, I found out that it uses a
JST PH 2.0mm 5 pin female plug. However... After some experimentation, I come into a dilemma...
The stock USB cord is this generic black cable. I prefer the more resilient quick detach cables with the aviator separator, like shown here:

I have all the parts to build my own cable, which I got on this website:
https://zapcables.com/diy-detachable-usb-cable-kit/The part I can't decide on, is if I should have the aviator cable terminate into the 5-pin JST, or if I should mod the case to fit a USB-C breakout board instead, like this one:

I personally prefer the breakout board because it would be easier to switch USB-C cables, and I wouldn't need to open up my keyboard case as often. But then I need to modify the case to fit the board, the cable routing channels would probably not fit, and I'd have to drill+tap M3 screws (?) to keep it secure to the keyboard case.
Also.. the small 5mm Inner Diameter EMI Noise Cable Clip I bought, is too big to fit inside the keyboard housing. I know the happy hacking topre boards have a large compartment to house one in the back. Sucks!
Anyway, I was curious if other people run into this problem when modding their keyboards, and how they resolve it.
