Guys am i missing anything or ROI takes too long?
Estimated profit per month is around $319.35
The ANTMINER S7 costs 1823$
Correct me somebody i hope to be wrong in this calculation? If i am right why should we invest when it take just to long to get the money that we invested? and the difficulty is increasing

Your caution and restraint in not buying one of these units, at their current USD value, is an intelligent choice.

It would be a safer bet to purchase and hold ~$1800 worth of BTC on the markets, given the current price of BTC @ ~$230 USD.

Back when bitcoin was steady from 400 to 600 buy and holding back then over hardware would have fucked u up
With the drop in BTC prices

Now we are in a total different environment hardware costs too much and BTC is too cheap, if anything the BTC prices of this gear should be in line with miners profits not a WAy manufacturers to fleece the little guy.

Anyone buying this gesr at these prices is simply a hardware addict kik most of us here

Me... I kicked the habit I dont buy anymore for the sake of having the biggest baddest toy out there anymore, I run the numbers and .. If it don't make dollars....you know the rest

P.s I made a point of buying 2k worth of bitcoins today
It came to 8. Something.

I guarantee you these s7s wil never mine you 8btc in a year less the 3k kWh power you have to pay for.

Even with free electricity it would take six months to farm back 2k

I was thinking the same, it is much easier and more profitable to buy ~1800$ bitcoins and hold for a year maybe and sell and maybe the profit will be the same as mining. And you are not stressful, no electricity bills and many other things...

Hoping for a coupon for one of these bad boys.

It'd be much appreciated if someone could throw one of those s7 coupons my way, to use (not to sell).
Thank ye.

This might sound silly, but what I had in mind was 3 people purchasing 2 miners and split them into 3 unique miners with 2 hashing boards each. Ofcourse this would require a extra controller.

I'd actually be up for that..

It is spring here and Australia and the temperature gets over 45c here in summer so I will be looking at adapting my S7's to the Syscooling S5 cooling kit

http://shop.syscooling.com/goods.php?id=51

I would prefer to not get into a debate about the kit itself but would like to see if anyone has any suggestions about making it work. It appears as though the S7 hashing boards don't have screw holes in it so I will likely have to rely on thermal adhesive.

Also does anyone have any experience with the thermal strips supplied with these cooling kits? Is it worth using, is it a thermal adhesive or just a paste?

I understand that Syscooling had some dramas with a water pump they were supplying when they started out. The pumps that came with my radiators are a sc-750

http://shop.syscooling.com/goods.php?id=26

I am a little unsure as to whether I should trust these pumps because there will be about $2500 riding on each one.

I would rather use water cooling then to use A/C because if I go the A/C route I won't be able to run as many miners.

Cheers

I agree with not going into drama on it.  But if you do I suggest an upgrade on pump, don't go with that.

I had 2 C1's I used - http://www.ebay.com/itm/381066536924?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT on and works good.  So if you find a way to watercool by modifying i suggest a pump similar to that work great and lot bigger resivour.

You could also use evaporative coolers (swamp coolers). Those work quite well in dry climates. Here in Washington state, the highest outdoor temperature we saw this summer was 43°C, and with our evaporative coolers and zero A/C, our indoor temperature never got above 30°C. Typical intake temps for us are below 26°C unless it's above 38°C outside.

That said, Antminer gear is usually designed to run fine in high temperature environments. 45°C is definitely above the recommended operating temperature, but I've seen Antminers run okay at that temperature with no reductions in hashrate. Of course, if you have temperatures that high or higher plus positively pressurized hot aisles, then you might have a problem...
