Neglect electricity cost?  You realize that 4 of these units burn 14.6kWh?  At $0.10 cost, that's $35.04 a day, or $1065.80 a month.  Somebody's going to notice .  Let's say that each unit gets the advertised 5.5TH/s.  That's 22TH/s total.  At current exchange rates and difficulty, you're looking at expectations of about $59.50 a day.  Subtract out any power costs and that's your net daily profit.  Using my example, that's $24.46 a day.  You need to realize that as the network difficulty adjusts, and the exchange rate moves up and down, your profit will adjust accordingly.

Hello, what do you mean by "project"? Buying a single one? What is your electricity cost?

Technicalities aside, it is not a hugely efficient miner, specs note 0.66w/gh. So if you're somehow about to get the unit at a good $/gh, then maybe it would be profitable, assuming you have cheap enough electricity.

You would need 240v and power cables(i believe).

I do not think its a viable unit for house mining, seem more like a unit for large deployments.
