Where to put 980 ti hybrid radiator in cm690 ii

[Oakley999]

I'm currently trying to install the gpu but there's no space at the back as my h100i pipes are in the way, and the pipes are too long to mount on to the side, I still have all my drive cages and there's cables getting in the way at the bottom, even though they're all zip tied into the corner, any help as to where I can put the radiator would be great thanks

I could rotate the h100i radiator to move the pipes out of the way but I don't know how to un mount the radiator as this pc was custom built
