yeah, that's not gonna work if you put it in a rack and something above it. the arctic fans push way not enough air through that case to get sufficient cooling. if you go rackmount, you need to use what rackmount cases use. something like those: https://smile.amazon.com/AC-Infinity-HS1238A-Cooling-120mm/dp/B004YTSB7C/ref=sr_1_15?ie=UTF8&qid=1504956105&sr=8-15
they will sound like jet engines, but they will push enough air. also think about the directions of airflow. i would turn the gpus around, push air in at the front and out at the back.
you can also try to use special 1U cooling racks that just push air from the top down to whatever is underneath it.
rackmounting in general works and looks much better than open air frames. it's just like every server build: loud ;)
also, you need to make sure that the room itself is properly cooled. if the fans push in 100°F air, there is only limited cooling capacity.
Yes. I use this one.. You have to clip the cord to run it through the drain hole in the back, but your drain will still work for condensation and you won't know it's not part of the design.
Then the fan runs on a standard light timer.
I bought a speed controller that connects from the power outlet to the fan.
The first one you linked is FAIRLY similar to the one I am using right now - https://www.amazon.com/gp/product/B004YTSB7C
I picked a higher flow model as I like to lay a piece of furnace filter over it as a pre-filter to keep SOME of the gunk floating around in my basement out of the humidity bucket. It lets me go a little longer between scrubs to clean out the bucket. I'm all about lazy efficiency ;-)

Technically I disagree, if only because I'm running a 110CFM fan at 50-60% speed and the fan definitely pulls through the filter. In fact, running it faster pulls through so fast the air doesn't get filtered well -- a different but related concern. I'm using this. I say "technically disagree" because with all that said, raising that fan's speed is the best way out of this situation. OP, be sure to get a speed controller for that more powerful fan so that you can make fine adjustments.

I can't speak on the effectiveness of the filter yet. I'm on my first grow and I have no need to use it yet.
