I'm sure someone has already tried renting an office that had utilities included to set up a mining operation.  I wanted to see what issues you ran into and how long it took for the landlord to catch on.

I was thinking a 15 unit 1.7T per operation (running ~1.1T at ~900W per).  Free electricity and cooling for $220 a month office lease (~165 sqft).  Would have to provide own internet connection ~40 a month for a total of $260 per month.

At current difficulty/price I am looking at a >$1000 a month profit and an 8 month ROI.

Anyone have any insight/thoughts?
