Fascinating, but this system is not going to have a pressurized hot air / cold air isle containment? Your airflow may have potential issues, have you considered the combined CFM of the individual miners creating static pressure bubbles?

One way we overcame a lot of our cooling issues was simply tripling the average CFM to KW standard that most data-centers use.  By removing heat rapidly from the environment (think wind tunnel) we have had 0 cooling issues.  How have you accomplished this or expect to accomplish this in your open floor / white-space model?  Hot-spots still exist, and blow back is your biggest enemy (when miners pulling air into hot air isle exceed CFM airflow of supply) they basically then push hot air back into cold isle and suck it in again (thermal loop).  You won't notice this until you start to get to at least 50% capacity.  Just wondering how you guys deal with that aspect.
