is this already out in the market? if so any reviews on the performance? this might crush the bitmains dominance over the bitcoin network hashrate and people will finally stop crying about china controlling bitcoin/bcash lol looking forward to this technology
No. At the moment, we will have to wait until at least October - 5 months, before anyone will see a unit.

It was in all of their press releases, presentation, and also still currently on their pricing page, although that now says shipping November 2018. FAQ still says end of October for June orders.

Sad we missed that, broker got the invoice a moment ago. We'll have to contact buyers and soak transaction fees for those who don't want to wait or position funds for another buy.
Thank you.

Did you pay using the email they provided to you after you completed the purchase application? or was it done on their website?

I just do the marketing for mfb but from what I understand is they send BTC/BCH addresses and wire information. You pay to your preference, no need to contact them directly unless you need to. B2 is sold out though, B3 is available for Nov.

there is a "spec" for it on their site, what states: Daisy Chain MAX 32 units.. .whatever this means, I am curious if anyone has some actual info on this! ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) go to B2 press release where some features are explained more completely. Only requires plugging one of them into the internet, and the rest hook up to eachother

Just like the Avalons....saves on running multiple ethernet wire all over the place, although the Avalon's start to get some weird errors after five are connected. Still five is better than one.

my post on avalons hooking up to the rasp pi controller was deleted.
There was a point to it. So I will re phrase
max avalons on a controller = 20
I have found 12 on a controller work far better then 20.
so 60% of max = really good results.
100% of max = more errors.
No one knows what the max will be for this new gear.
I caution buyers that what is said to be the max by the builder may work or you may need to do 60% of the max daisy-chain the builder of this gear says you can do.
So if you are getting a lot of these keep in mind you may not be able to the full amount the builder say that you can do.
Since this is speculation I will speculate that 50 to 65% of the number said to be the max by the builder will work better with less errors then 100% of the max the builder says you can do.

Does anyone here have anything to add about the double fans?
Will that actually be more efficient than 1 bigger fan?
I'm quite curious since they don't mention that part in any of their FAQ

Just that they are not stacked fans. Each is a single fan like the Delta GFB1212VHW that uses a 76.2mm deep housing to accommodate deeper fan blades. edit: added DigiKey link to the Delta fan

I wondered about that.
I also wondered - why make a machine for which that's necessary?

Ok, so my original thought was correct about the b3 fans?
Aren't these rated at higher wattage than 2k? You'll at least have voltage "control" in the UI to bring it down to b2 spec. Still "vaporware" till we're closer to release date. Way to early GMO, you've already changed your design in a few months. Maybe soon they'll figure out a third model that has the speed with efficiencies we want to see by Oct.
@sidehack: I imagine your question is rhetorical but for the sake of discourse. ..
Retooling can be costly so I imagine design is centered to manufacturing, look at Obilisk for example. It will be hard to break the narrow tube design, packing heat sinks in a jar like they're cotton balls. Maybe someone will be bold and change the game for the industry.

You mean like literally everyone was doing before the S7 became popular? And like Canaan still does?
The narrow tube design with heat sinks packed in like cotton balls is a lazy way to put way too much power in a tiny box. A tiny box nobody's asking for. A tiny box that substantially reduces system reliability (not just by baking the crap out of your silicon, but by relying heavily on overtaxed mechanical components like high-speed fans and assumptions about ambient conditions - these would die rapidly without chilled, dust-free air), in a time when breakeven returns will take a year longer than the warranty period.
It doesn't really take boldness. Just takes common sense, a little bit of extra R&D and prioritizing providing durable quality hardware to the customer over making immediate large profits.

Profits are a huge motivator, that's why it would be a bold move to break the norm and why other people conform to meet the expectation. In a sense at this point to deliver anything else to market would be "rebellious" even as we agree completely, that it would only make sense to do so to deliver a quality product.

They are not taking advantage of other designers. use avalon 841 heatssinks use halong t1 style firmware for speed control 82 watts per th fast speed 15 th 1230 watts medium speed 13 th 1066 watts slow speed 12 th 984 watts easy peasy

Only advantage is in the way of using manufacturing already in place. If you mimic you can turn units quickly since you don't have to retool a factory especially if you own your own facility (turn time is even more accelerated).
Canaan is a great example of design intuitiveness. Still though the concept is the same, just more thought into delivering a better product (my personal opinion) with subtle but effective changes. As a buyer you're rewarded with it. If you're following my post on heat here lately I am less nervous about my avalons then my antminers. Would love a T1 but with prices probably looking at other units.
Back to the b2/3 concept, if you're facilities cooling is on point it doesn't matter. Stuff the jar, suck the power (if it's cheap), mine blocks. These things aren't made for me and mining at home.
Then any miner wants a solid combination of hash and efficiencies. My point is that GMO is taking this model to the extreme. I hope companies pick up on this and look to adjust in a better direction like we're all saying in different ways. Better efficiencies, cooling design, and voltage control.
I don't need a miner that looks like Arnold would have over his shoulder ready to fire from a helicopter.

In-place mfg such as what? PCB assembly houses do not care about the shape of boards, they can make and stuff any shape/size you want. As for the housing, Bitmain uses an extruded tube and ja an extrusion die cost $$$ to make however there are many extruded tube/case profiles that could be used 'off-the-shelf'. Canaan and GMO are using machined frames and simple bent covers which of course means that they could use any style case they want to.

I appreciate the insight but the argument isn't they can't, but why they don't. Ease, profits, turn to market. Or is there more I'm missing?
