Cool.  One thing I'm interested in and am going to test out with the one motherboard I ordered is cooling. 

Rather than getting a case with a bunch of fans, I'm wondering if an "open air rig" with a box fan in front (and maybe in back) would give enough airflow.  My idea is to get a metal rack (ie. one you can find off of amazon/lowes) and put several miners on the shelves.  Directly in front of the shelves would be a stack of box fans - one stacked on top of another. Will probably build a wooden frame so I can easily stack them and put them in a wooden rame.  On the back, thinking about having a bunch of box fans again, or just a big exhaust fan (the one I have right now in my basement is 3,000 CFM) to suck the hot air out.

If you have a box fan, would appreciate any tests you could do with the 1080tis and putting the box fan in front of the motherboard/GPUs on the highest fan setting.

I'm not opposed to buying a case with fans, just trying to figure out of there is an easier/cheaper way to cool a rig - especially running multiple rigs.

Or if you/anyone has any other thoughts, please let me now.
