Mine came in today as well. No duty

Set it up in about 1 hour, however I trashed the controller and used my RPi with Scripta. Works like a charm.
Currently running at 850, but I will try 900. We don't need fans right? I can remove them if I am only running Scrypt I think. Cut down on noise and save energy.

great

I guess u could remove the fans.
Never thought of it ever before but

and the new GB has raspberry Pi controller not the gridseed one
