I would also control dust measures and have air ducts in more than one place to circulate cool air in and warm air out

 You need to get airflow INTO / OUT OF the garage, not just around it, or overheat will happen. Fans in windows are a good place to start.

I don't know what lead you to this conclusion. I've read many positive feedbacks here about Bitmain hardware and nobody's home burned down.

That won't be a problem at all. The miners will be outside my living enviroment but I really have a problem with ventilation in my garage. I'll have to put some fans I guess to cool the whole setup down and make some natural ventilation. I'm sure of one thing - the fire extinguisher will be there for the worst case scenario 

 You're confusing Bitmain gear with KNC, especially the Neptune and to a lesser degree the Titan, where KNC designed the units to exceed the spec on the connectors for power they were using.

 The issues with the Bitmain S7 have been the crappy job on applying the individual heatsinks to the mining chips, and the price being too high for most folks to ever have a reasonable chance to ROI them given how short a time they appeared before the reward halfing (and then the diff increases ended up making them pretty much unprofitable for most WELL before the halfing).

 I suspect the S9 might have the same heatsink issue, but there is no way to know for sure before folks start recieving them. It shouldn't have an issue achieving ROI if it's as long-lasting as the average S5 was (or most S7s to date that didn't have heatsink issues or had said issues fixed properly before use).

 The S5 was actually a quite solid unit, as long as you didn't push the OVERCLOCK way high or try to run it with low-airflow fans in the name of keeping it quieter.
 Mine had no issues with an Iowa summer without A/C in a place that the airflow was fair but not great, ambient temps inside were running 6-8 degrees above outside temps most of the summer. Not exactly the sign of a unit that "Oftentimes" "goes up in flames"....

What would lead you to this conclusion?   The S7 has been ran by many many people including myself.  The S9 looks to follow the S7 so I predict it does well.   And it's efficiency no other miner on the market is close to is why everyone thinks it's great.   You have to see how it is a big jump in efficiency.

I'm guessing your trolling with the comment's about flames.   I think if anything someone using wrong gauge cable's or crappy Y cables is at fault, and cheap PSU's is more commonly reported.  Can you point to 1 house burning down due and cause being a Antminer?  I just have not seen it .... which again leads me to think your trolling.

S9 had been released and will ship on June 12th, in 4 days. Trouble is it's crappy, why everyone thinks it's mother's milk, I don't know. Bitmain hasn't released anything of quality and value since S3. Their S5 and S7 have sold well but that doesn't mean jack shit. Oftentimes, their gear goes up in flames if you look at it funny. China-built, China-quality. I hope you buy them and your house goes up in flames. Don't blame me, I told you so.

i'd rather choose antminer and fyi wait for a while after halving, i heard that bitmain will release s9, i don't know if its true or not.

It depends  on his cash situation vs his amount of power situation - if he's got lots of cash and low power limit, it DOES make sense to go efficient in order to maximise his hashrate.

He mention's he has "free electricity" so I'm not sure why you would send him to the cloud for mining.   "Free" electricity he will make more mining at his place.   So kinda not the route I see him going.

With "free" electricity he does not need the latest and greatest efficiency so I think S9 would not make sense for him.  Waiting till having and snagging some bargins on S7's likely is best thing he can do.  And this assumes he can handle noise/heat.

Go for hashnest o Bitfury
If electricity is a problem, second hand miners are probably better and much cheaper

If not, an antminer S7 or S9 are probably the best ways to go, though if you purchase miners second hand they will arrive much faster and with power supplies

One thing to remember regarding your "free power". I expect there are limits on it as you mentioned, but furthermore, at a practical level a miner converts electricity to heat. A 1000W miner is just like a 1000W heater. If that is going to impact your living environment in some way, be aware of it. Some miners are also quieter than other, with the general being that the hight the wattage, the louder it is. If you are thinking of putting two S9 miners in a closet, what would it be like if you were to put 3 hair dryers, on full blast, in there round the clock.

Would that be a problem?

Honestly I would start off small to.  If your budget is 5k I would not go all out right away.  Get less gear and make sure you have enough money for cooling, shelving, PDU, etc (depends on your setup).

But if you start out small it's easier to add more and you can do it hopefuly easily and you will know your setup's limits.  One of the worst thing for miners is buying them and not having all parts ready, so you have downtime.

Thanks for advise. I actually already thought about waiting for the price to come down. I think before I'll gather sufficient information about the rigs the price will come down

Right now, your best choice *IF* you have enough money for 3-4 of them would be the S9 - but IMO wait for the price to come down some.

They'll do the best job of "loading up" your amount of free power the most efficiently - and nobody has announced anything that can top their efficiency by a noticeable degree, much less has anything competative in production RIGHT NOW as a miner.

I have something around 5-6 kwatts of free power per hour.

s-9 uses 1.4 kwatts per hour and Avalon 6 uses 1.1 kwatts per hour. Does it mean that s-9 is a better mining hardware than Avalon?

There was at one point with butterfly labs, although a lot of the stuff was still made out of country.  But we saw how they went and scammed so many people and lost a lot of people money.  Horrible shipping... etc.  So there was decent sized maker in US, they just were horrible and we have not seen a commercial sized one since (that I know of).  

Best if going by efficiency is going to be S9.  Bitmain is kinda beating others to releasing next gen it looks like currently.

Well if want to buy USA gear you need to build a pc and mine eth coin.

If you want to buy from China the s-9 or s-7. From bitmaintech or Avalon 6s from Avalon.

How much free power do you have?

10 kwatts or 2 kwatts  or more or less.

The s-9 uses 1.4 kwatts per hour.
The s-7 uses 1.3 kwatts per hour
The Avalon 6 uses 1100 watts per hour.

I have a few used s-7 s and Avalon 6s if you want.

There is no US made hardware....Bitmain & Avalon (aka Canaan Creative) are the only ones selling NEW stuff.

Best bet I would say is old S3's or if you got money,new/used S7's  

Hi guys. That is pretty much my question.
Which firm of mining hardware providers is the best one?

I want to setup a mining rig (I have no problem with a free access to electricity) but I don't what hardware I need to buy. There are so much thing here: Antminer (a bunch of models), Bitfurry and other stuff. I have no financial problems and ready to invest 5000$ into my mining rig. Should I buy China or US made hardware? Which one is the best one?

Thanks a lot in advance of advise
