Actually, I'd like some comments from you...
- Would you like a USB miner or are you happy with standalone RasPi controlled unit?
- Do you feel modular design is important, or would you prefer a nice tidy box?
- What about form factor: free or rack?
- What dB level are you comfortable with?
- Internal custom PSU or ATX?
Standalone with ethernet - doesn't need to be a rpi, I don't want to have to manage a load more linux boxes, any <10Euro micro that can talk to a Stratum proxy will do.
Probably nice-tidy box or board on heatsink.
Free
Noise level - about the same as a PC if possible
External PSU
And I think these things need to start at 50-100GH/s - the network's moved on from 10GH/s being a load!
