Corsair HXi PSU and Fractal R5

Does anyone here have experience with Corsair HXi and Fractal R5 (or perhaps Fractal Define S)? My only concern is that the fan grill on the HXi PSU is slightly raised which can cause compatability issues with some cases when installing the PSU fan facing down. Fractal R5 does have standoffs for the PSU so there might be no issue depending on the grill positioning in relation to the standoffs.

Google pictues just told me the fan grill of the psu isn't raised on the hxi series
