based on my assumptions of difficulty movement (primarly a ~30% drop within a few weeks of halving), seems like with free power ROI takes 5-6months. With 0.07/kwh its closer to 10-12 months.
I can have one hosted at $0.06/kwh (+15% tax), and am likely to pull the trigger if it falls to 3.5BTC via BTCUSD price swings. At 3.9BTC, its a gamble - it would probably break even but after a full ~16month lifespan ROI would probably be 10-20% at most
So how long does it take to "Break Even" (aka ROI) if your expected -30% difficulty change doesn't actually materialize? A 30% difficulty drop is roughly equivalent to a 420PH decrease if I am looking at things correctly.

We will need to see a btc price above $800 to really have this make any kind of sense. Here is hoping the happens.
I see no reason it shouldn't. It's already begun rising from a very steady price, the halving is only a month away! We'll have to wait for the halving to see though. I've got good feeling BTC price is not gonna go anywhere because of the halving. BTC halving price adjustment already took place last year when the price doubled from 225ish to the 400+ we've been healthily sitting at since this year. You don't think it will skyrocket like it did after the last halving? I see no reason it shouldn't Like you said we've been healthily sitting at the same price for a long time, I feel this current rise in price is only a signal of the halving that's coming.

We just saw a huge show of force on the network. If i was doing calcs id be factoring in another 600 ph increase over the next 3 - 4 months This is def a waiting game> Huge gamble to buy now before halving.. https://bitcointalk.org/index.php?topic=1484047.msg14975076#msg14975076Best Regards d57heinz

Wait and see what happens with the halving before putting any serious money in. Too many unknowns at the moment.

Quoting from the first page... sorry Not sure what they have in mind for the controller board? It's populated for 4 Hash Boards and 2 Fans but has provision for 20 Hash Boards and 10 Fans...
...
Now you know what kind of beast they have in their farms 93.3 TH/s with 10 Delta fans on push pull.... tasty

Looks like the same fans so I'm going to guess that they're just as noisy as the S7. Can't wait to read a review on these but they are just too much for me to risk right now.

Since Summer is upon us, as soon as I get notice that my last 2x s7b18's I ordered last night are shipped (great timing there ay what?) I will be ordering an s9. Right now I have 4x s7's running at home being 5.2kw worth of heat load being added to what my AC has to handle so is a no brainer there: take 3 of the s7's off line and replace with the 1 s9. Introductory pricing be damned the combined miner and AC power savings make it a winner for me. Best part is that the ~1,350w load fits perfectly with the 1,800w (2.2kVA) Cyberpower always on-line UPS at home so no worries about dropping >14THs from low power line or blackouts (also have a permanent home generator to handle extended outages) . For those wondering, got the GE 11kw whole-house genset ~ 3 years ago after my area of Detroit had a 2-week long blackout -- during a big summertime storm the local substation literally blew which in-turn damaged the feeders to it ... Of course since then the longest outage has been maybe 1/2hr at worst At least for now I can replace the last s5's I have at work with a couple of the displaced s7's and will have spares...

If you think the price is good, buy an s9. (imho $1200 is realistic)
If you speculate the price of BTC will rise before the halving, buy BTC.
If you are sitting on the fence unsure but in the future know you want s9's and need to spend funds then buy hardware for them in advance. ie. power supplies etc and wait a month or two.

This happened to me. I paid within 7 minutes of my order. It showed expired for about 3 hours. During that time I flamed them with emails and support tickets. They did not respond to any of those, but I did get a "Paid" email confirmation about 6 hours later. 21:00 GMT.

Nice! Impressive specs. which equate to timing of release. So you may be close to roi by or just after halving but what then. Who doesn't want one? I think it still might be more viable to by btc now and hold. The otherside of the coin is if btc jumps in price at halving this is the only miner to have. Still, good job again seeing this through to completion as always.

I like the hash rate, but that price though...Give it a few months and it'll drop in price.
