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?
PI - no reason for USB other then troubleshooting made easy. if USB, people would simply run it to a PI
BOTH - modular is great, but a tidy 300GH box would be beautiful too and may be easy to run airflow through
FREE - but if following above suggestion, a rackable premade box would be nice
MINIMAL - I am happy adding my own fans, and a silent or quiet miner is nice
CUSTOM - a 'custom' 12V PSU is obviously most cost-effective
I like to picture 2 products coming from you:
1) system similar to the V2, modular and free-standing nd the most cost effective without psu included
2) system similar to the asicminer cube - standalone system with housing, heatsinks,fans,and PSU capable of 200-400GH that can be racked or stacked. i would pay a *small* premium for the simplicity and good design that could come with this option
