I have two rigs, a Threadripper with 3 2080 ti's, and an i7 4790 with 3 1080 ti's. I was thinking of consolidating some of the cards into the Cubix and running that through the Threadripper. Was thinking that with the Xpander, I may be able to run 5 of the cards through it. I have no idea if that is feasible.
