Crypto mining on GPUs, well, I thought that trend was over five years ago. But then I sense you want to make money with this rig, so fun is not quite the intention of this system Wink

I think you also missed the part that it will be custom build open frame so heating and airflow would not be a problem. Right now I have 2 Asus Strix OC 1080Ti and I am satisfied by their performance.

You're takling about 12 GTX1080Ti or the equivalent of 3kW of heat dissipation. Even in an open frame that's an issue. Or maybe especially, since you have no control about the temp around the GPUs. In a close case with radial fans on yours cards you can blow a lot of air in and out of the GPUs. That's bulletproof, as long as the room temps are low enough. In the open case though these cards are producing a lot of turbulence, especially at high speed. To make sure that each card is not interfering with the others, is unnecessarily difficult.

But it's not only about airflow, it's also about reliability. FE-models are build for long term stress loads like hashcat. Gaming models like the Strix are, well, for gaming. Their selling price includes a lot of marketing costs and cheaper components cover for that with MOSFETs or the fan-bearing of minor quality.

That's ok, but since some methods of cracking need way more speed between GPU and memory that makes a big difference. For most cases x1 is fine. But, of course, if you try to feed a lot of external data into the GPUs with a fast hash like MD5, they might suffer performance hits by the x1-speed.
