Dual E-Atx case?

[danielmjakob]

I want to build an x399 pc and a x299 pc in the same case. The mobos I want to use are the Asus Zenith Xtreme and thr Asus Rampage VI Extreme. I have already checked cases like the Phanteks Enthoo Elite, Thermaltake Core WP200, Corsair Concept Slate, and the Caselabs Magnum THW10. After speculation I can confirm non of the anove can fit two E-Atx motherboards. I am sure a desk case like the one Lian Li makes might be abke to do the trick but I want an actual PC case. Before anyone comments "you can't afford this" "This is a waste of money" or "What do you even need this for" If you don't have an answer or contribution to my question don't comment. Thanks

Buy two cases that take an eatx board.
Siamese them together. (insert massive DIY skillz here)
Done.

I doubt you'll find a retail case that will do this.
