This video is not a good representation of your setup as it shows an EVGA 1070, which the presenter later switches to an MSI card at the end of the video.
Actually, when I take a closer look at your proposed setup, it seems like NZXT is saying that it will fit either the 1080 with front fans only, or the H100 with a shorter GPU.
If you calculate the difference between your card's length and the maximum allowed by NZXT, you will find that it is a bit over 25mm. This is the thickness of a regular fan, and obviously does not take into account the thickness of the radiator.
So, No, it will not fit both the 1080 and the H100 in their normal configurations.
You could install only one fan on the H100. It will still cool your CPU adequately with just one fan.
My build, linked in my signature, has a very close GPU fit also, and the way I was able to install it was to have only one front fan. Your proposed build is slightly different, but this same idea/concept can help you in your "case".
