I'm really getting curious now when they will have their first test miner built.
And the real stats like hashing power and Watts will be a big question till then.
Not to mention the heat problem, I'm afraid these Vipers will catch fire within an hour or make more noise than a Boeing 747 taking off...
Not too worried about heat, based on other high-hashing designs I've seen in action. I'd be worried that it works, that they have the firmware proper, and there are no import/customs issues.
