Hello,
what exactly do you mean by looking good, you can only see the vertical graphics card anyway? You only need a riser cable and possibly a bracket. Lian Li offers such sets.

Hoi, thanks for the answer. I have already tried the same thing with the other version of the case with the result that I now have to pull the DP/HDMI cables into the case, which doesn't look very nice. I know for the smaller model there is an extra bracket that also adapts the back and then provides a nice transition so that the cables can be connected there. I haven't found anything like that and thought maybe someone has already tried something.
Greetings
