Going vertical

I want to get a riser card for my bottom most slot on my motherboard to have my Graphics card vertical rather than horizontal, this is purely for astetic reasons though, I was wondering where to find a pcie riser that didnt put my gpu facing downward into my PSU. i havent found any yet and i know a flexible one would work but im not sure how i will secure the card inside the case.

something like this, so the fans are facing outward towards the window.:
