Each rig will have 4-5 video cards with a usb drive. I am thinking about 5-10 rigs. Depending on how fast i can sell the coin. if i keep selling a t a good step, I'll keep adding rigs. I have most of the EQ now so this will save on $$$.

I did not think about an open case. Might be a good idea. I'll let you know.
Thanks
