It's good looking, but I'm not really sure with performance and durability about this products. In my opinion, six PCIe slot it's enough (stability needed), except you are using Linux based OS. Sometimes people forcing 7-8 or more GPU's using Windows based OS. Mining process needs a stability. Don't force your devices.
This. In terms of the amount of time you'll spend trying to get those cards to work you'll earn your money back just going down a more reliable route. Lessons learned the hard way through experimentation and trying to use PCI-E splitters or m.2 -> PCI-E. The time invested and the troubleshooting just wasn't worth the small gain of adding an additional 1 or 2 GPU to a rig. I've found it's much better to just build another. Linux this isn't so much of an issue but windows mining you run in to resource issues and all sorts of wonderful bugs that'll keep you up until all hours trying to fix.
