how much you pay on electricity costs every month? round $2,000 what do you pay per KW/h ? thatīs not even that much for over 120k Khash .035 per KW/h Nice and cheap eh? I'm guessing you don't just build a 120Mh/s farm without a little strategy first. It is a second job, for sure. I started small, worked out the kinks, and now have a process that I simply repeat. Standardization is a huge plus.....makes an operation much more efficient. |

We have a lot of the "silliest" answers here, from people who have no datacenter or AC experience. You put up a bounty, you get stupid spammers and beggars.
Before qualifying any answer as silly or stupid, I think we need to know some additional considerations such as the amount of money he is willing to spend. If we take into account the kind of unit he is considering to buy, that sounds more like a kind of garage project, in the line of DIY and low cost solutions. In the company where I work, we recently did an investment in a cooling solution. The company spent a bit more than 50,000 euros (about 80,000 USD) in a solution based on in-row equipment from APC, like the one linked below. This was a very small datacenter with a power consumption much lower than 40,000 W http://www.apc.com/products/family/index.cfm?id=379So, if someone is willing to spend an amount in the range of 3000~4000 USD, maybe the silly solutions are those intended for real datacenters. May be, if he had a budget in the range of 100,000 USD he would be addressing his doubts to a professional cooling consultant. May be he would be ordering and paying a whole study and a project instead of being offering 0.25 BTC (about 180 USD) looking for ideas into a community of unknown people. This. I am looking for low cost, DIY solutions. This will be built out in space not originally intended for Crypto mining. I want to keep expenses to a minimum.....no need to spend all the profit on cooling the damn things. |

I design and build or rather used to....
I dont want your bounty but will happily offer up my 2 pence worth.
Not a concept i would choose, cooling is more complex than that....
How many servers are we talking? what are the BTU Raiting etc.....
How will air "flow" work around the space, will each server get enough cooled air
Why not free cooling??? just high speed fans in a small space and extraction can be enough on small setups.
Its not as simple as your question makes it
I am not sure of the BTU rating, but I will need to dissipate upwards of 40,000 watts. Air flow would be a bit tricky. I was planning on an intake and exhaust fan to get rid of humidity. The summer here are brutally hot....can get up to 110 F. high speed fans don't really cut it in those conditions, at least they haven't the last couple years. |

I am in need of some technical advice from those in a position to know. In building out a new "data center" for mining, I am considering different options for cooling the space. I am interested in using a unit like this: http://portablecoolers.com/models/PAC2K482S.htmlMy understanding is that evaporative cooling can pose a risk to electronics, as the air might become saturated with moisture. I am in search of some expert advice on this subject. 1) Is this a feasible option? 2) How risky is it? 3) Can the risks be addressed? 4) If not, what is a better option? Most comprehensive answer, with the best information gets the bounty. Thanks! |

Heh... nothing like linking the product where you can buy it cheaper than you are asking.
Meh, Because the price of BTC never changes rapidly. |

How about 7 BTC and I'll take over the risk that they never deliver or deliver 2-3 months late? Do they allow customers to transfer an order or are you planning to forward the miner on once it arrives? 7 BTC could be worth $25k in two months...  Thank you, but we will pass. We can transfer the order easily. We prefer to accept $ for this transaction. |

Im looking for a decent mining rig to mine alts. I need about 2000kh/s. Anyone selling?
I will sell you 2,100 KH/s for $2,750 |

Bumping this. Will accept bank transfer as well.

There is something to consider, Majority of Asic companies has been late. Like Hashfast was suppose to deliver on OCT 31. Etc.
If Cointerra is 3-4 months late, that reduces the profit massively and buyer losses 1/2 his investment or more. This is only assuming if Cointerra is completely on time.
The gamble is if Coinoterra is on time, going by majority of Asic companies being late or a good 70-80%+.
Isn't a person better off taking $25,000 gambling it for $45,000 on Just-Dice at 1.6X multiplier of 62% chance?
If you really think buying a Cointerra rig is a mutually exclusive Zero or $45,000 gamble, well....I can't really help you. However, there are a lot of establishments online that will gladly take your action! |

Just floating this out there.
I have an order for a January delivery of the Cointerra IV 2 TH/s ASIC that I would like to sell. My partner and I were very early in the order process, and actually converted a December order into multiple January orders. We have been assured of being first in line for January delivery.
The price is $25,000, based on the following assumptions for the buyer:
Assuming 25% difficulty increase per jump (declining by 1% per jump), the buyer will score a tidy profit.

I'd like to buy one of these three, shipping inclusive to cont. US.
$500 for a brand new 290, shipped. Newegg has 290's for $399.So I'm going to have to respectfully decline that offer.  It was worth a shot. Just looking for used cards at a good price then? |
