From what I understood they were leasing over 100 machines, but that is just a claim from the twitter feed on Oct 6th.
If in fact the machines did exist, and were mining coins, he made off with a pretty penny in BTC.
I decided to give them a shot after speaking to Rowan over the telephone. He always answered any questions I had, and was responsive (within 24 hours) in returning calls and emails.
I was really excited to see my first monthly statement, which is what I thought the letter was. Turned out to be a big bummer.
