I wouldn't recommend putting that EVGA 1080Ti in a small case, trust me. I have that GPU in my RIG right now and even with the front panel off of the Define C with 2 140mm fans in the front and a 120mm at the rear exhausting she gets really warm while gaming, these EVGA 1080 Ti's dump heat, most of which comes from the back plate now I know it's normal for the Ti's to get warm and it's not a loud card either despite "popular reports" at 70 - 75c in my case I just couldn't imagine what it would be like in the Dan ITX.
A founders or AIB blower style would be better suited to the Dan as it would feed itself air from the side panel vents and exhaust as designed, rather than dumping lots of heat into a tiny space.
