I am fully riser free.. Thanks to my Seller Sidonia on aliababa .
I am running 6 slot and 8 slot boards with zero risers.
I'm actually mining on a personal gaming computer so a riser to separate my four cards from each other is the best option for me currently I think.
If you need some risers that ship from the USA, I'd go with these guys. They are a safe and reliable source in our experience.
