Core P3 Help

[Anoraked]

Hello!

 

I'm building a new PC and am looking to add a Elgato 4K 60 in, but from what I can see, the GPU mounted vertically will cover the PCIe slots.

 

I know I can just change the orientation of the slots that hold the GPU in place to mount them vertically, but that would probably be my last resort.

 

Could I squeeze the 4K 60 Pro in behind the GPU (for reference the Galax HOF RTX 2080ti).

 

Any help is appreciated!
 

Thanks!
