Long story short:

I have almost free electrical energy. I need your recommendations on hardware where the important things are: Price (to be low), TH/h (to be high), Reliability (No over-heating).

I'm actually new, but I made a conclusion that if the hardware consumes less power and gives you more hashs it's pricey, so if the power consumption is irrelevant (high.. doesn't matter) then the hardware should be cheap?

What's your recommendations? Thanks in advance.

Best regards from Riyadh :)

you are correct.  and i would consider ordering from this group buy.


https://bitcointalk.org/index.php?topic=735982.0  good price if  you have cheap power

How much "free"/cheap power do you have available? 1kW? 10kW? 100kW?

Thank you guys on your answers. Let's say I have ∞W of electrical power for veeeeeery cheap price.

Isnt the answer simply everything then?

Yeah, it is. But I want to spend less money for the same hash rate.

well you can buy the gear from asic miner  10 units are 7.9 btc  that gets you about 8.2th

If you have infinite power then just setup an amateur DC and host other's people miners and you can make some money out of that.

Why would you mess with all that?  If I had infinite almost free power I would rent a building close to mine and run underground cables to the other building.  I would then send the electricity into the other building where I sell it to the power company and make a profit.

I think that the power company will ask you a bit of questions about the source of your power. I think it's easier to sell the power to miners than to the power company. But I like your idea :)

Infinite free power huh???  This must be that mythical unicorn power I keep hearing about...

In Saudi Arabia (Riyadh) I would have thought the biggest problem was keeping the miners cool.  You may need almost infinite free cooling to go with the almost infinite free electricity.  

Well, infinite power = infinite air conditioning. We're also assuming that he has infinite capital to go along with his infinite power.

If you wanna get in, go buy 2nd hand dragon units.. should be able to get a few units pretty cheap..

Or, go buy older gear and run it.. might be worth it if you really have free power. (everything will be a waste if btc prices doesnt rise though)

there are many people on this earth with free electricity ...
this was the major advantage when using GPU's as the cost of GPU was same everywhere and the only variable was electricity cost which was huge..but now the asics has come the margin for electricity has come down and the device cost is also variable...so i would say whoever gets the miner/hardware for cheaper will win.so its not the who has free electricity but the guy who has free hardware or lesser priced hardware..

If you go by the calculation at current rate...you buy any miner even with free electricity you won't break even.because the hardware manufacture have already put up the price higher...so they are once with most profit not the miners.

An S3 going into production today produces roughly .74 BTC before flatlining. Cost is .66 BTC + Power Supply. This assumes uniform 15% difficulty increases. Now, if I model a slow decrease to 10% difficulty increases by the end of the year and flat thereafter, that S3 will produce 0.9 BTC before flatlining.

If you have free and infinite power, get a bunch of Antminer S1s and overclock each and everyone of them.

Some users are selling for dirt cheap, in some cases just giving them away.  If you could get 100 of them and with cheap server PSU's for like $75 per Ant S1, you'd probably be in the green by late October/early November (equipment costs only).

Cooling costs is a whole other discussion.

Go for Ant Miners S1, they are cheap now ! Gather as many you can afford.
You will have ROI pretty soon !  8)
