I have some new information regarding the cable assemble I hope this will help you guys.
J80 cable assembly line sequence as shown below,
Precautions:
1: Need to cut off the cable interface of the supplied cable (refer to Figure 1)
2: In order to prevent the line from getting stuck in the outer casing, the inside needs to be treated a little bit - the thickness of the outer surface is cut off. (Refer to Figure 2)
3: You can tie a cable tie at the position marked in green in Figure 3 to catch the bottom hole and prevent the wire.
4: If you use a wire socket, you need to polish the socket 0.5mm, the socket model is: eh2.54, 4P
If you use the indicator light of the lamp module, you need to remove the black horizontal resistor at NL.CL and change it to vertical soldering. Refer to Figure 3 for the red circle.

I put mine together this evening. I'll post some pics when I have more light.
Some notes:
Make sure the switches are properly mounted in the PCB before soldering. There isn't any plate to hold them in place while doing the deed so it's worth paying attention to. I messed up on a couple and had to reflow the solder joints to get them seated.
The LED cover thing. None of the screws seemed to fit.
Even with the cable is thinned like the pics above you're still going to end up clamping it between the two halves. The zip tie in the position shown will fit just inside the case and provide strain relief. If you want to zip tie it to the PCB too go wild, but I do recommend the zip tie on the cable as shown above.
The wiring as shown in the pics also worked fine with no issue. Soldering those thin wires to the PCB was a tedious though and I had to try a couple of times to get it right. It's really easy to overheat such thin wires.
All told it was kinda frustrating to build, but it makes for a really nice typing experience. I can definitely feel the PCB flexing a little as I type (67g Zilents). I could see this being by daily driver for the next while.
