What are the struts holding up the Coolermasters and what fan controller are you using? Thanks

Believe it or not, those are just a bunch of plastic motherboard standoffs stacked and screwed together. Great for adjustable height... not so great if you want something super stable.... but hey, They Work^TM
You can get a big bag of 100 for $12:

I also used some rubber grommets just to make them more stable on the glass desk. Grommets I've found are great for standoffs or as a make-shift gasket between Scythe fans and Antminer S1's (you can't place secondary fans flat on the S1 without some type of gasket to raise it a bit because the fan will hit raised screws).
A box of grommets of various sizes go for $7:

I mounted the CoolerMasters onto fan mounts meant for home theater equipment cabinet use:

The Fan Controller I use is the KingWin FourChannel FPX-001 which currently goes for $18:

I also use a molex to DC/AC adapter for the KingWin and fans which goes for $19:

Thanks for the detailed info. An inventive solution. What setting do you run the fans at to keep the USB units cool? Quiet?

Thanks, unfortunately they have a high pitched whine at full speed. I usually keep them at about 3/4 power which has the best balance between noise and airflow.
