I can't imagine the cops face when busting in on what they think might be the pot bust of the year only to find a miner and his giant computer 
To be honest, if someone asked me what i was doing with this, I would probably say "Search for Aliens, did you ever hear about the SETI project? And of course have my main computer ready running Folding@home or SETI@home
Im not sure if I should go with SETI oder Folding here... the SETI thing sounds a little more nuts. The other thing on the other hand is something people won'T comprehend. "You are folding proteins? What the f*
!" According to the FSA if you are mining you are emitting currency and therefore should be regulated .... Ha ha ha ! But yes they would have grounds, especially if you are smoking pot and mining at the same time...
I just started mining again, it was getting too cold in my office!!
