Hey - that was my post - I tried multiple ways to try and get it to install this afternoon.
With the ASUS B450i the length of the Black Ridge means that it overshoots the PCI socket so you can't fit a GPU - at least that's how it appeared to me after I managed to get it seated in the AM4 mounting holes by removing the included fan.
I may have another go tomorrow when I have a bit more time and see if I can just sneak the GPU in if I remove the heatsink but it's going to be an incredibly tight fit.
