After months of planning, stressing, and budgeting my mining operation is finally up and running! The electrician just installed three 30 amp 240v circuits/outlets, and I'm using heavy duty tripp lite pdu's to distribute power to all 19 miners. My makeshift hot/cold isle is working nicely and keeping temps in a very acceptable range. I'm using insulated tarp to keep the hot exhaust air separate from the cooler intake air so the exhaust can be vented out of the window, and I'm using a 14,000 BTU AC to assist in the cooling process. Let me know what you guys think or if you have any questions.

Since I still have plenty of electrical overhead and the miners are running at good temps and in a well managed condition, I may offer hosting to a couple of people for a couple machines at a very competitive rate and see how it goes, then offer a more legitimate hosting solution when I scale up in the future.

I think you should replace those tarpaulin with more solid thing like plywood.
Also tarpaulin seem to be more easier to be burned

Yeah, plywood would definitely be a good long term solution, but this was much easier/quicker to work with and I can't imagine it spontaneously catching fire just from relatively high ambient temperatures.

Overall, i like how you set it up.
Its seem split the room between cooling room and hot room is better as i also do for my farm

Good lookin' setup.

I'm 99% sure those are Bitmain APW5 power supplies.

Oh my god!.Did you just build that alone with your own funds? 19 antminers? seriously? How fast can that mine? This is the farm site i actually want to develop also. I guess the real profit is just starting from now. Hope the investment is worth it. could you tell us how much you paid over of that? its ok if you want it private.

Yeah, the hottest that any of them are running at is 61c. I guess server farms use hot/cold isles for a reason, it works!

HagssFIN guessed correctly, they're the APW5 power supplies. I originally ordered the APW3++ but I got an email and they supposedly ran out of parts for them so they shipped these instead. I think they're considered an upgrade though, being able to handle much more, so that's cool.

Nice, how much you pay electricity ?

I pay $0.10 kW/h. Not the lowest electricity rates in the world, but it doesn't even matter when the L3+ is so profitable anyway. Don't let people tell you that you can't make money with anything above $0.05 or $0.08 for electricity.

How much money did you spend for that farm?  The miners, power system, racks, everything?  Call your power company and see if you can get a deal on a better rate for high use, like for business industrial rates.  Or tell them you have an electric car, some give discounts for that.

Bitmain site says $1291 each for those miners, times 19 = $24,529 , plus power supplies, plus racks, PDUs, electrician work, etc.  You've got at least $40,000 sitting there!

I paid more than $1291 for each because I pre-ordered them months in advance, from that surprise batch they released at 6 am. Well worth it though!

Antminer L3 is a LTC miner correct? If so then you should post this in altcoin mining section, Anyhow I love what you have done, Neat and beautiful, A few days ago my brother told me that his friend has a workshop, Apparently they have been using a lot of electricity but with the magical help of some kind of device their electricity consumption was reduced into almost half, They are paying half the money of the times when they weren't using that device, Do you have any clue what that might be?

Is it more profitable to mine an Alt coin, specifically litecoin, rather than bitcoin? You got a very nice setup and the amount you invested is huge for this. I'am just wondering why you opted to mine litecoin rather than mining bitcoin. just a noob question perhaps.,

The L3+ is more profitable and more efficient than the S9 so that's what I went for.

The S9 isn't more profitable than the L3+.

L3+ profitability, ~$17.13/day: https://www.nicehash.com/profitability-calculator/bitmain-antminer-l3?e=0.1&currency=USD
S9 profitability, ~$14.20/day: https://www.nicehash.com/profitability-calculator/bitmain-antminer-s9?e=0.1&currency=USD

Even if those numbers were switched around it wouldn't matter, they're both very profitable.

S9 is cheaper than L3+ Smiley Mining BCC with the S9 will give you 18$/day (non nicehash)

But yes i agree, very profitable

I remember back in the summer of '13, I had 11 GPUs mining LTC, and with the difficulty holding right around 1,000 , I was collecting about 10 LTC per week for a few months.
