Bitmain may have changed their mind on releasing the R4 for sale and have now put up a blank page at https://enshop.bitmain.com/adv/antminer-r4-silent-bitcoin-miner.html where six hours ago a very polished website laid out all the specifications of the new home miner.

But, there is a cached copy of the website they took down at https://web.archive.org/web/20160826021158/https://enshop.bitmain.com/adv/antminer-r4-silent-bitcoin-miner.html

The time is right to give Bitmain real Trust Rating.
https://bitcointalksearch.org/user/bitmain-156878

My negative rating stay, until Bitmain does not delete negative trust against BitcoinNewsMagazine .

Bitmain Has multiple forum accounts and posted invalid trust items against BitcoinNewsMagazine. Abuser forum Trust Rating system.

EDIT.

29.august.

Bitmain has removed his false accusation against BitcoinNewsMagazine .
Thus, a sign of good will, I will take back mynegative feedback.

More OT, about ROI...
Current price for the batch 12 s9 @ 12.9THs gives $123 per THs. PSU not included.
The R4 @ $1k and 8.6 THs is $116 per THs... ~~PSU included~~.
Hmm.

edit: Rechecked their gallery - shows a separate PSU.

this is a good remark...
but R4 are new...
they will be reliable???
for sure if i will buy, i will buy one to check reliability.

Bitmain APW5 PSU (2600W 220V / 1300W 110V)
https://bitmaintech.com/productDetail.htm?pid=00020160728031839203Gq83S56J0622

Whoah, that's one beefy PSU!
And the price is beefy too! 300USD

If true that is not to far off of current PSU from Bitmain assuming you mine 2 R4's off new PSU. The APW3 is 120 right now so 240 to run 2 s7/s9 (with 2 items shipping could factor in some to possibly higher. If price is right 300 the new PSU is going to be higher price per miner. But with silent and run's off 120 or 240 will be interesting to see how sales of them are.

Actually not bad price for plug-and-play all the way from 110v up to 240v.
But 7 pairs of PCIe, making only 14 total? Rather odd number no? I would have gone with 20 for the option of 2 s9/s7's (barely) @ 240v or 1 s9/couple undervolted s7's @ 110v in.

edit: I really should start using more of the IBM DPS2000 supplies (with your breakouts & cables) I have. Right now only have 1 in use. Just that getting the Bitmain ones got to be too convenient since if I needed one I ordered the same time as getting a miner.
Still use the one setup like I did for my old s5's - just set the PSU an inch or so away from the the intakes so the miners do the airflow required. No fans needed.

Sweet, a 2600W PSU with 14 jacks. I sure hope they're 18AWG so people use a buttload of splitters to run more than one miner and end up melting down the wire. For less than that $300 I could get you two 1500W PSUs with 12 16AWG cables each. I mean 2600W in a single PSU is pretty great but I still expect to be disappointed.

Given rated 845w total load and 6 boards giving 140w per-board my bet is 1 PCIe power jack per board.
wonder how well it would fit in an old s4 case?

Or the 4U high case from the miner A1 chip Dragon clone (1.1THs @ 1,350w) that AMT finally sent me 8mo after ordering...

It is probably 2 boards with 3x PCIE power connectors each.

Took another look at the pic on Bitmains site and yer right - it shows only 2 cables running from the controller to the hash boards. So, 2 hashboards slid into the partitions guiding air and giving nice support.

If you are on about rack mounting it, it looks like its about 20 inches long so I would imagine the boards would be too long Sad

Could you mount the boards length ways in a old spondoolies case tho? but I would imagine you would have heat issues toward the back of the case imho.

Would be willing to give it a go if I had the spare cash

Well if the more common 19" racks are out, there is always the EIA 24" wide ones used in the AV industry...
edit: just looked, 610mm is 24.01568" so even EIA racks are out. But still, I see a lot of aftermarket case possibilities for this. Or branded casing from the retail chains. It *is* targeted at the home market after all so maybe just a couple per household. Ya know -- a mass-consumer Bling item Wink
