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?
1. Raspi is best, available everywhere in case of malfunction. Al this proprietary stuff is a pain to replace when needed.
2. modular, easiest to service
3. free
4. not an issue, I am using very silent shark fans
5. atx, again available everywhere. currently using Corsair AX1200i, shows me the Amps on every PCI power connector!
