My thoughts after some time with these:
Don' use power bricks. They can't properly power them. I bought the highest rated 12v 6a bricks and they weren't up to the task. Two burned out completely, and another kept putting the pod in zombie status.
The ones connected to a PSU (EVGA Supernova 550) ran 20 days before needing a reboot.
Of my six units, two were giving me issues with shutting off or inability to reach higher frequencies. I replaced the stock fans on them with ones from cooler-master that have twice the airflow rating (

The 550 PSU is now powering all 6 at 200mhz and putting out a combined 536 GH/s which is right in line (slightly better) than the predicted output.
As I live in the south and it is 109 here with the heat index, I have 2 140mm fans adding to the fan power and neither the noise nor heat are bothersome. Excuse the lack o cable management, was still fiddling with them this morning. They are mounted in a line to maximize airflow through the heatsink channels, and when it's really warm in my office I add a third 140 to the end to help push the warm air away from the pods.
Bottom line: I love these pods, and they are perfect for summer mining in a small home farm.
