I have replaced my BFL 12GH/s by this R-Box at 32GH/s ... here is the setting to use it (you can update the first message with the picture if you want).

Picture are here : https://bitcointalk.org/index.php?topic=885753.msg9848021#msg9848021

It's for solo mining ... replace "localhost:8332" with your pool if needed.
-u = username (on pool or RPC server)
-p = password (on pool or RPC server)

Thanks for this subject, it have guided me to choose a replacment device ...  

PS: fan has been replaced by a less noisy ... that why the temperature is not 39-42°C ... but 61°C.   no problem, and ... no noise !
