I don't think you'll have to cut the case. There are some radiator mounts you can buy which should be able to put in push with fans blowing out of the case. I am getting these so you shouldn't have to drill holes :)...
I actually just purchased your Acrylic 3D bezel this week with the wrapped case with the intention of it fitting a GTX 1080 TI Mini. Was that before or after the redesign?
