I dunno... Current design leaves power flexible... You can repurpose all kinds of older/cheaper PSUs
AND when next gen chip is out, you could upgrade one board at a time too instead of replacing whole device if power is interconnected

I think because of the plethora of different PSUs out there, it's most economical to just use longer pci-e 6/8 pin cables to connect to source PSUs and modify/vut solder as needed. breakout boards for dell/hp/ibm servers come to mind...

yes, a host controller can be a computer, a Pi or an x24-specific microcontroller (perhaps will be released here too), 32 boards can be linked together (8 devices) the controller connects to one board, rest are cascaded (serial connection).

Heat sinks and the volume they take up is the issue here not weight. That is valuable real estate in a DC and even in a small node at home. Why did AM build themselves a modern high density cooling solution?

They already built the future. This offering is not it.

This is what the industry wants, maybe this is not what the home user wants it, but this is how the game is going to be played:

Not sure I completely agree with that. Immersion cooling is definitely the future but it is quite a ways off before it becomes economically viable for most DCs let alone most homes.

I predict that a very efficiently deployed immersion setup would cost ~$150/kw. For those with cheap electricity, it would still make sense to go with air cooling. For example if you had an an efficient setup ($150/kw) and $0.05/kwh electricity you would be saving ~1/3rd on electricity so ~$0.016/kwh or about 1 year to break even.

You simply have to admit that for the average home miner and air cooled DCs with cheap electricity, this is quite an attractive machine.

Side note: I am 99% sure that AM has already made a high density immersion solution and I'm sure they will give it to anyone who asks (not positive about that last part)

In other words: The heatsink is the case.
Well thought out - should bring down deployment costs.

Regarding air vs. immersion cooling.
Immersion cooling is still a job for the professionals. If I understand the open source nature of the new block erupter correctly, the air-version is supposed to be a DYI kit for the little guys.

AM is not stopping their immersion development. So anyone building the cubes will be in direct competition with the DataTank boards likely with the BE300 chips or the next gen they might have on the drawing board after that. Gotta keep this in perspective if AM is going to produce 100s of PH/s worth of chips or more a significant amount is going into data tanks via that single wide or double wide immersion blade. Welcome to the end home miners.

And by the way... there is an air cooled version not unlike the spondoolies SP10 SP30 configuration have a look in the link above. Enjoy your cubes. Not sure if you can get the chips on a board configuration that narrow given the power going through the copper for air cooling but I bet someone thinks you can do it and have an air novec cooled boards in the same exact configuration.

Your estimations are based on what?

Given what numbers are available most smaller miners need to be moving out of Sha256. You can hope and dream these units will be cheap but no one is going to make them if they know it is going come back and bite them when they can't sell them at the price they need to. Given that there are only just a few of those those smaller board makers left who would target the remaining and ever dwindling small miner market I don't see them taking on this risk unless it is a Chinese based fabricator and even then doesn't look too promising.

If you got the numbers let us see it. Put up a spreadsheet and show us where these will make money for the fabricator and the miners. Please I would love to see your projections and do not forget to add all the costs in for the end users please. The numbers we have run do not look too promising even at greatly reduced price for BE200 or 300 chips.

I am talking about PCB costs, chip costs etc... you can't throw out difficulty projections and estimates of final miner costs and think that is the spreadsheet I am thinking of right? You need to do some due diligence. Time labour etc... just to get this all set up. Where will you source parts? Which PCB fab? Etc. Fabbed where? Shipped where? PSUs? etc etc.

There has be a factor for profit you will need before jumping in on this. Look at the nightmares already out there. Who you gonna call? And I do mean this seriously? Who?

It is all well and good to project the rosy numbers but in reality there are fewer and fewer people willing to build this sort of thing because it just isn't worth the effort especially when there are currently working designs that will probably beat this design with the next chip generation in much more datacenter friendly configuration that uses the same chips. Again seems like a lot of aluminum.

There are already chips in design that will be out in August. I think your 5 - 7 month window is a bit myopic. Anyhow great you are big on the design. I hope it works out. I have serious reservations given the chip and the price of these units when you factor in everything. I will let you guys get back to working out who will fab out these designs up for you. Thanks for listening.

Done our numbers and we are not building a cube.

Remember you are promoting this unit so the burden is on you to prove it not me. All I am saying is good luck nothing more or nothing less. Having a design doesn't mean it will be priced right. Lots of work needs to go into that if you want to make it profitable for the fabricator. That is where all your optimistic projections hit reality. What is the bottomline price. If it is too high then no one is going to buy it. Have a look around plenty of examples of that happening right now with very similar designs. Be careful and good luck.

Join the WPC and you can see all the numbers you want. Not my numbers to give. Again you are trying to sell a fabricator on this not me. So sell it. If you can prove it is profit worthy someone will jump on it.
