Normaly just mine with 3-5x S1 ants and buy new as i resell them, but bought a bigger stack of miners than normal so time to setup a shelf i guess 
First layer of unboxing done:
Scavenged some psu's off old servers in my storage unit:
The 12x 310gh/s will generate around 3900w so need to figure out some cooling.
Got 2windows in my storage room so gone put up a shelf between them and play mcgyver with some ducttape/duct/fans.
Just need to figure out how much air i need to move...
i am guessing that funeling 2 miners (620watt) into a fan each would be a drop in the sea? 336cfm total.
edit:
Best ive found sofar is a 10" 72watt 2300rpm, rated 800m3, 2 of them would give 941cfm.
not too bad pricewise at 30$ each.

dayum...why didn't ya just get a cheap attic heat exhaust fan like me? 1300cfm should be nuff to vent the heat of those cards...it's handling 4kw heat for me 
How loud is that thing?
Looking at the webpages of varius stores in my area they all sell the same exhaust fans that are 95m3h (3354cfh) so only 56cfm at 15$. How loud is that thing?i am guessing that funeling 2 miners (620watt) into a fan each would be a drop in the sea? 336cfm total.

good luck with that...hell i'd just try a walmart special fan in the window...like the big ones...not a box fan and point the miners towards it
and see how it handles it...course depending on where ya live...or maybe buy 2 hehe and get a wind tunnel going
