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?   Grin

ouch 0.35/kwh, and I thought 0.2 was high
