Thanks, my doubts were regarding the thinness mainly.Major concern with GPU fitment is card length and thicness.
According to NZXTs official product information "NZXT H200i - GPU Clearance: Up to 325mm"

According to PowerColors website "Board Dimensions: 300mm132mm53mm" Where 300mm is the length.

The NZXT H200i supports dual slot cards, and the 5700xt red devil is dual slot.
So yes, it will fit.
