I have two setup already, I hope my  adapters arrive today as I'm using the BE controller with bfgminer as a proxy to hash on a different pool. Are you going to hook it up to the rpi first? I really would like to get two more but I'm not sure how many the pi can handle. I always look forward to your posts as you're very good at documenting everything and showing us pictures of your setup in the process. Thanks for sharing your knowledge. Any word when the GB will open again?
