It would have been nice if you actually brought something to the discussion. I'm assuming this means you disagree, but you've not explained yourself or clarified a position. You can set up a perfectly fine mining rig, without risers of any kind. I've known many people to run dozens of 1080tis at once that have never even considered risers. There are endless amounts of problems that pop up with the usage of risers and the benefits they provide are mostly nullified by better planning/design. Their usage can be avoided, while saving money and without losing power is what I'm talking about. You can set up a rig with less of a chance of failure, for cheaper without them.
