Hey guys, I'm actually doing something.
I went and started the cutouts for the back panel of the case. This is the most complex piece of the case, so everything else shouldn't take too long in comparison. However, my friend's shop doesn't have any sort of milling machine so I improvised. Drilled a whole lot of guide holes along the two big cutouts so that later I can finish the cuts with the jigsaw with more ease.
Here's the other side with no tape so you can see it more clearly. Left side will be the place for the I/O shield, and the right side is for the adapter panel that takes in the GPU and power connector.
Closeup.
Flipped back around, showing also the countersink holes I made for the four M5 screws that hold the panel to sides of the case.
The top hole is at an optimal diameter, allowing the screw head to go a bit further in so that there are more threads to attach the joiner pieces at the other side. The bottom hole is flush to the surface but the screw won't penetrate well enough. So some holes need to be countersunk a bit more. I'm really eyeballing it with the hole diameter, but the alignment of the holes are all measured out.
Another closeup to show how the GPU bracket fits in with the adapter panel that I'll put into place. The bracket looks like it runs into one of the screws, but since it's a tapered head it actually is free of interference on the opposite side.
Next up, finishing the cuts and making the adapter panel.
