well guys it was a tough one.
the one thing we were trying to achieve was portability, you cant really sell a turn-key system when its on a wireframe rack.. the rigs never worked out as planned and we had to redesign everything from scratch.
we tried building proprietary 12, 14, and 18 Titan 4u servers using SBC's with passive backplanes and utilized Protocase for the chassis. 2 of each unit later and we were still kinda stuck in a hole not really making anywhere near what we wanted to.. we sold those units, making most of our money back but still a setback.
so we did the only thing we could think of, buy up all the 1080ti's our budget would allow and all of the necessary hardware to support it. we ran out to home depot, put every wireframe rack they had onto a couple dolly's and 2-20 days later got our parts in from amazon, newegg, and many other retailers (that was a pain). assembly was rough... zip-ties saved our lives.
after reaching ROI in about 4-1/2 to 6 months it was pretty uphill from there, once bitcoin reached 20k my sponsors quickly cashed out and made well over what was initially spent. When GPU prices skyrocketed, they sold all the 1080ti's in anticipation for the GTX 20XX series. with CPU mining coins like Yenten, Koto, and Raven we have been able to see continuous profits on the 6950X's while solo mining, also been playing around with Titan V's seeing really great results come from that as well!
All the best guys and thanks so much for the help!
