I was hesitant to try vertical mounting my gpu, but it was surprisingly relatively simple to install and worked out of the box without on my rx 580 2048 gpu for a nice, clean look. Luckily, my Fractal Focus 2 case rear pcie slots are bridgeless so I simply needed to remove all the covers and had no compatibility issues. You may need to cut the metal bridges between each slot to allow for proper installation.
