This may seem paranoid, but I would suggest removing the "Bitfury 400GH Miner" marking from the case. If you're going to host this with a third party then you may not want to advertise to the world its intended function/purpose.
I am definitely interested in this case. This would also be a concern of mine too.
Great work so far. Just thought I would mention my interest along with all the others. Hope you can manage to ship these along the same timeline of the August Bitfury Release.
I also concur regarding removing the labeling, as making this device as discreet as possible would be prudent. Perhaps a simple logo would be best. As far as the case, I would prefer closed, making it look like a standard server, easy to stack or rack up, while providing a bit more protection. Those who want it open air would simply remove it.
