All of our equipment is burn tested after final assembly/testing for ~24 hours on a live pool (In this case, EMC).  After the burn-in, it's taken off the rack, packed and shipped the same day.  We do this for both the singles and the mini rig and the singles PSU's (we've had a few of those go bad, so now we burn those in as well). 

We are not mining with any ASIC equipment at the present time.  You can be sure there would be a big announcement if we had turned up the ASICs on a live pool.
