EVGA started showing off designs for a unique, and enormous, case in 2015. It has since been rebranded and has undergone some minor work at the plastic surgeon to emerge as the EVGA DG-8 series of chassis. EVGA sent me the flagship model, the DG-87, that features an integrated fan controller to operate intake and exhaust airflow individually. EVGA took some interesting chances with this design: it's bigger than just about anything we have ever used, it rotates the case orientation by 90 degrees so that what was normally your side panel window is now facing you and it routes all of your cables and connections through a side section and out the back side of the case.
If you haven't seen it before, this video is worth a watch. Expect a full review sometime in August!
