Nice setup. What are you using to suck the hot air out of the hot room?
The front
The back
I have now about 30 Asics in this room, still have room for a few more that i am getting in a few days.
I used MDF 16mm to divide the room into 2 smaller rooms , used a CNC router machine and trilled squares of 121 square mm, so i could easily insert the fans, then dealt with the 1mm with tapes to try and perfectly isolate the the intake from the exhaust.
difficulties i faced:
1- the alignment of the rack , as i used cheap racks to save cost, and they are not very flat, neither was the floor, i knew this from the start so i had my initial design on the CNC to keep a margin to the downside, as i can lift the miner up by putting anything under it but cant force it down ! , so it made more sense to do it this way, that's why you can see some miners sitting on a small peice of wood " the left-overs from the mdf sheets i used".
2- the initial work on the CNC machine, it took me sometimes to perfectly align everything all together, the metal poll in the middle "visible on the second picture" was taken into consideration while drawing the design which made it less efficient, but still worked. the pole was important as the size of the mdf sheets i had access too were either not large enough to cover the whole space or too large to sit on the cnc table, therefore i had to cut it two 4 pieces and used the pole to hold it.
advantages of the current set up over the previous ( before the split)
1- the miners run cooler as most of the hot air has no way to go back to the intake
2- way less noise
3- potential of better and easier use of the hot air in the hot room ( maybe put a few egg incubators in it and they will crack in hours
)
4- in the summer it gets extremely hot here, up to 45 degrees c is normal >: , oh that is (113F for fellow Americans ) ,,so no matter how much airflow is put, they will still get hot, so i have to use an AC to let the miners inhale 
some cold air or they would melt. this was not possible in an open room as i would need a dozen of ACs to beat the hot air,but now i only have to beat the ambient temp which is enough by using a single 24000 btu AC
so you can actually use anything to isolate, whatever is cheap and at your disposal.
* I have very cheap power rate so i could care less about an AC running 24/7 in the summer, and the ACs here are designed to do so.
* i know the spacing is too much, but i had a lot of room with FIXED power, so 40 miners will be it for this farm, an upgrade is NOT possible
i did all the wiring myself, including the electricity, if you have any question regarding that , feel free to ask.
cheers.
Farm no.2
So here comes the second farm, actually it's the first but i haven't had the chance to share it with you guys, so i had to manually reset one of the miners today and decided to take a few photos and share my humble set up.
The set up is pretty similar to the other farm > https://bitcointalksearch.org/topic/my-mini-mining-farms-set-up-wiring-5087770
but this one is a a lot smaller.
so here is the view from the outside
i used gypsum board to build this small farm, don't ask why , i always use the cheapest martial i have at my disposal
same split set up. hot room to the left, cold room on the right ,notice that i don't have an easy to open door for the hot room since i don't need to in there often.
here is a view for the racks
3 rows, each row takes 4 miners, there is currently only 8, i sold the other 4 for a good price, bought another 4*s9s should be here in a week or so.
here is the 2 intake fans, they are not industrial , just the once you would use in a kitchen, and they are doing pretty good, i have 3 of them attached to the roof to exhaust the hot air from the hot room, sorry i forgot take a picture of those, but they are the same exact once.
and here is the main and sub circuit breakers
so the main cable that runs to the main breaker is 16mm2 (5awg) , the main circuit breaker is 80 amps at 220v it should handle 17600w, but i am only consuming something below 15000w.
I have 4 MCB of 25amp each , 1 is for the AC , and every 4 miners are connected to 1*25 MCB ( 3*4 = 12 miners).
the 16amp MCB is used for the switch and the fans.
you can see in the image, there are 2 wires going out of each MCB, every wire is used by 2 miners, the wire is 6mm (9awg).
so every wire goes to 2 plug sockets as shown in the image below
i use those sockets only to cover the wires, i am not a big fan of using plug sockets for over 1kw , i cut the end of the psu cable, and joint it directly to the cable using the same blue joint kit that you can see in the image of the circuit breakers, the initial set up was using those outlets but then i realized that it was a bit risky as those sockets were not very good quality.
some people think it's not the best practice, but i don't always good by books, i prefer real life experience and practice, and jointing the miners that way has always worked well for me, i had bad luck with using outlets/sockets, but not a single problem using these joint kits , plus i get to save some money with this set up.
also notice that wiring + breakers set up might not be something that people who go by the book agree with, but this has been going well for over a year and not single problem.
the total cost for building this was about 400-500$ from scratch to end including just about everything except for the miners of course.
edit: the place is quite dusty, am planning to clean it this weekend
