What kind of hash rate are you picking up? I hate to be redundant if you mentioned it in the video, but I don't have any sound right now so it wouldn't do me much good. It seems like you might be using more parts than needed to get the acquired goal. Beginners would be better served by fewer parts IMO, so with this being the case you would probably be able to cut down on all of these cards and just go with a pair of 1080TIs that you find for a good price. All of these cards would be taking up much more electricity than a couple 1080tis I would think and they give you more of a chance for failure with so many moving parts. More time spent RMAing and all of that. I suppose one benefit would be that when something does fail you would be out a less significant portion of your hash rate, unless it turns into a domino effect.
