I am going to part with one of my Avalon 6 miners. It has been up and mining for about 4-5 months with no issues.
Controller firmware has been on 20151111. Haven't upgraded as things have been stable. Average hashrate as of this morning is 3651GHs. Miner has been in a air conditioned warehouse and never modified, overclocked, etc. I will include the Pi B+ V.1 controller w/ SD CARD and all original accessories.
The EVGA 1300 Watt G2 power supply and TP Link Wifi bridge are also available if you are interested.
Make me an offer...BTC or ETH only. See pic below for actual unit being sold. Thanks for looking.
