I don't understand why people say this is not a hobby. I started making PC hashing rigs couple years ago. I had fun building the cases to hold six video cards. Then tweaking all the configs to get the best results. I got up to three rigs running before I started selling off parts. I used money I made from selling off computer parts and the LTC I earned to buy ASIC devices. I used to keep track to see how much profit I made, but got tired of doing that; that is not the fun part of this hobby.

I used the PSU's from the computer rigs to power the ASIC's. At this point I am definitely in the profitable range, but its not like i am getting rich doing this. It is a hobby and I really enjoy it. I have ordered one S7 and looking forward to playing with it too
