then you could have over 2TH (2.3 - 2.7TH out of 1 unit), however the PSU is not included.
You can use the server grade PSU to lower the expense if you are in the environment with no flammable items around the mining operation. Other wise, high end regular ATX computer PSU to power them up!
Quiet (in the same room as me)
Preferably wireless, but can be ethernet.
The more power efficiency the better
If it comes with it's own PSU or it is built in, that would be great too!
I currently have a s3 that I got for $200 Canadian with a Power supply which seems like a steal, but would love to get more hardware.
Thanks!

Get a antminer s4, run the quite fan mode to get the fan speed down to 2800 rpm. Pretty quite guy.
