If I'm reading that right, it's equivalent to 6 or 7 1366 Bitaxes. They'd use 72-84W for that same hashrate. BUT.....at a cost of $500-1000 instead of 40 bucks. The Hex would hit that low end. Still a lot of cash to un-ass for similar hashing, even factoring in the extra electricity cost. Operating cost difference would be about $15/month where I'm at. That's about 3 years before you break even on a Hex. 

I'm still gonna build one, though. 😂
