I joined the forum just the other day with the interest of obtaining some bitfury's, and the drillbit board sounds like a great concept.

I would pull the trigger to participate in this group buy much sooner, pending concept photos and/or actual photos of your drillbit system board, and the couple of bitfury sample chips with a "barntech" on  a piece of paper in the photo, or whatever. It's simple and silly, but it would authenticate the group buy for me personally.
