I got the mirror black version specifically for the grommet and included shroud. The RGB and USB C on the I/O was also a huge plus.
On the top of the PSU cover, the hole with the grommet. I will have to ask Corsair directly. After doing some more research, it looks like some cases have this hole and some to not.
Did you have to modify the case for the PSU pass-through? I am probably buying this case in a few weeks and none of the red/black/white ones I have seen have that hole - Only the new mirror black seem to have it.
