I just took these out of my mine and looking to sell them. I have 18 units total, two units can be piggy backed to create a 1.2Th+ miner. I usually see 1210Gh-1245Gh.
I believe with a high efficiency PSU you can get 610-620Gh out of these at 600W (I believe this is at the wall). These units are quite and have a heat output that is not like a hair dryer. I would consider this a good home miner if you have low cost electricity.
If you buy two units to create the complete 1.2Th miner I will include the Raspberry Pi B Controller with software for free. I have the original packaging to ship them in as well.
Buyer pays shipping or provides shipping labels
Buyer will send first or pay for escrow through TomatoCage or OgNasty
I will test fans and unit for full hashing power before shipping
I am open to offers at this point, I will post my preferred price tomorrow after I have had some time to think about it.
NOTE: The stacks below are 2 units creating a 1.2Th miner.
