Not a very good picture, but here's one of my Bitfury rigs that I'm tuning / troubleshooting. Waiting for a couple cases from Spotswood to arrive next week before putting them into permanent homes.

Have this one running more-or-less stable at 531 GHs ATM but troubleshooting and tuning continues through the weekend.

(Out of sight, two more fans blowing on the unit)

Big thanks to Buzzdave and Yvonne from MegaBigPower for being super folk to deal with.
