Hi again!
So .. came up with the idea to mount the GPU with a 90 degree angle
And create a structure for it so the system can be shipped if needed.
I had to enlarge some holes in the PCB.
And change some block stand-offs.
You can see I also mounted the PCI-e extender for more stability.
And .. to the radiator.
And as last, a 6mm nickelplated copper bar instead of the pci-panel
Till next time!
