My msi gtx 1080ti has a dvi port, and it could be tricky to remove it.
However, with practice, i’m doing it with no big trouble (i’m also able to keep my cpu cooler in place) Please note, before to unmount my gpu, i’m removing all red cover on unused video plug of gpu (dvi, 2xhdmi and 1xdisplayport).
Most cards have a dvi port towards the bottom, it's not an issue because you can lift the card halfway up before you have to tilt it backwards. If you have a dvi port like this that's near the top of the GPU bracket, you can only lift the card about 5mm up before the dvi port blocks further removal. So you have to tilt it back, which is easy in most cases, but for some reason in the Cerberus you can't tilt the video card back at all until you've pulled it out pretty far.
I suspect the space for the little tabs at the bottom of the GPU bracket is too tight or something like that.
