This is definitely not a scam.  I received my two units last night, and they are both hashing away in the garage just fine at roughly 220GH/s each.  They are certainly loud and my units were poorly assembled.  Since they are in the garage, the noise is bearable.  On the shoddy cases, it's not a huge deal, as they are miners, not artwork. 

As far as ease of setup, it was a little tricky getting two PSU's into the case and plugged in - very tight.  But once they had power, connecting to the network and setting up cgminer took 5 minutes.  Also, they run a similar OpenWRT linux to the AntMiner S1, so I was able to SSH into the machine, set up api-allow and see the status on CGRemote.  Easy-peasy.

I'm running them with two Corsair CX750 PSU's each, and they draw about 950Watts from the wall at stock 1400Mhz.  I've tried to run them at 1500Mhz and get roughly 230-235GH/s but power draw increases to 1050W or so.  I'm not sure if it's worth to overclock given the ~5% increase in hash rate but ~10% increase in power consumption.  Any thoughts from others?

Overall I'm happy with the purchase and hope to make some ROI in a couple of months.  My concern is power use, as my rate here in CA is very high (0.35/kwh!!!).  I might need to sell them in a month or two to someone with cheap power to maximize my return...  Anybody want a 6week preorder at $1500 per unit?   

There is an error in this. We all chose to buy units with either dollars or bitcoins. If dollars, then there is no ROI till we sell coins. If bitcoins, then you either convert to dollars at either end or stay in bitcoins at either end.

Technically my ROI then is zilch, as I have not converted my bitcoins to dollars. I have however bought a Chili, chips, and a really good Papa John's pizza which is far more than the 169 I have invested in dollars. So my ROI is positive.
