okay the inside height should more than clear a vertical mount from the bottom (and then 280mm rad at the front)but for the horizontal option, the inside length won't be able to clear if you're using the stage-2 standoffsinside length of CX is 329mmstage 2 mount is 58mm + Zotac 1080ti arcticstorm is 300mm (not sure if it includes that PCI flange on top)totalling 358mm (-10mm ish for said flange, but I still doubt it'd clear)if you're not using the standoffs and want the upside-down horizontal mounting (with the rad staying put at the bottom) then be prepared to cut the front vents. you might need right-angle cable adapters for the HDMI and DP connections as wellEDIT: I haven't considered PSU placement yet, and I'm starting to think there might be placement issues if you're using a full ATX PSU in the bottom vertical setup...
