Other How to figure out GPU and Riser positions when designing a sandwich-style case?

[Deleted member 12074]

I am designing a sandwich-style case (like DAN A4, Ghost S1 etc.) and wonder how to figure out the screw hole positions for the riser cable (or rather the board at the GPU end) and the GPU cutout positions (at the back panel of the case). Maybe someone who already designed a sandwich-style case can help me with this? Are there any design resources available to make this easier? Are these cables even standardized? I am currently planning to use a 30cm Riser Cable form the DAN A4 v3.

dont forget that pcie 4 is released
as far as I was aware, the cables are not standardised ....

Thank you, I am already using these models. They are extremely helpful for cutout design, but how to figure out the position of the screw holes for the riser cable in relation to the GPU cutout position?
