Hi,
MinePeon is a great system for most mainstream miners.
I installed MinePeon on on of those, but can not recommend it as:
* Too much tinkering and MinePeon does not play well with the custom cgminer 3.9 in this Miner
* The RPi is low profile and MinePeon uses a decent amount of ressources
If you still care, i will upload an enhanced firmware image
in this thread tomorrow evening.
