what did you pay for the rig?
did you purchased it new or second hand?
anyway stay with linux distros as they are very stable compared to windows
£1100 - Second hand
I am currently using SMOS - Might try HiveOS next.... but I have it up and running and hopefully configured right... I will have to wait until my first payout to confirm this - But It is mining to my specified wallet address so lets see what happens.
I am going to do more reading up which coins etc... but just starting with ETH at the moment.
