Unless you want to solve your particular cooling situation, you'd probably be better rewarded if you target something like the Antminer S1 or S2 with water cooling.  As I see it, the main bottleneck in the near future will be efficiency in GH/Watt, as with rise of difficulty mining might stop being profitable if the electricity cost becomes greater than BTC reward. Unfortunately the Av16 boards are far from being efficiency champions (unlike the earlier Bitfury based Drillbit devices.  I'll keep running mine while they can, but sadly just like BE's, they are approaching the 'departure lounge'....
