Looks like this is pre-order and it is shipping october mid? Seems not profitable for me 
What part of it suggests it's pre order?

The ethernet controller is the same of the Tube ? You have a new firmware ?
...
The fixing of custom ethernet controllers' problem is still under way though.

Agreed.

1 btc for shipping is too EXPENSIVE (400+/-) for shipping ? normally about 200USD. Please revise shipping rates. also guys pls do not forget to add in psu cost to run these. i'm sure pricing can be reviewed. FC you can do much better !
$400 to ship 75KG is actually pretty inexpensive.

1 full device consumes approx. 1100w (conservative) so you will need a 1200w psu which costs approx. USD 200 each so x 10 = USD 2000 (excluding spares)
It draws 1000W from the psu. 1100W is at the wall.
You could buy the most expensive ATX psu or you could use a modded server psu for ~$25/1000W.

10 full devices will be a jungle of spaghetti wires. looking to see some new design & improvements to eliminate the jungle of wires.
The boards are already chainable, what more can they do? They only need 1 controller per 32 boards and there's really nothing they can do about the power cables.

here are some of my broken math :
10 devices + shipping will be 14.9btc = USD 6013 (Preev rates as of now)
1 full device consumes approx. 1100w (conservative) so you will need a 1200w psu which costs approx. USD 200 each so x 10 = USD 2000 (excluding spares)
so for 14TH total costs to run is roughly USD 8013 excluding any exchange rate fees so round up to USD 8100 by the time it reaches your door step & that does not include any DOA's & RMA's issues.

why bother pay 14.9 BTC for these when they can only produce like 9-10 BTC ?
So I take it you have a magic crystal ball too?
Mine says these can easily break even with cheap electricity.
How many days for ROI with what electricity price?

buying BTC sounds much better.
why bother pay 14.9 BTC for these when they can only produce like 9-10 BTC ?
plus I need PSUs to run them, plus I have to pay 24 % import tax, plus i need space etc etc.

still can't ROI at this price 
Just like always. We will not buy this, right? 
Wi'll buy BTC instead. September 22, 2014, 03:47:57 AM
Just when I was about to buy 125 tubes, this comes up. Now I need to buy a whole bunch of these!
Post a picture with all of them installed here: https://bitcointalksearch.org/topic/--7216 when you get them.

Oh so 10 full sets so >14 TH/s for 13.9 BTC that's pretty good!!
Plus BTC1 shipping = 14.9
Why is shipping not included as with the tubes??

So this is a nice way of saying: Yes, it indeed has the same bugs.
No, there won't be any stratum problem using cgminer with Raspberry PI.The fixing of custom ethernet controllers' problem is still under way though.
September 22, 2014, 02:44:19 AM
Does it have the same internal software problems as the Tube?
Or is the stratum implementation fixed this time?
Hopefully your custom cgminer version doesn't have the same problems also.
The cgminer differs from the main branch in only the communication to the deviceOr is the stratum implementation fixed this time?
Hopefully your custom cgminer version doesn't have the same problems also.
and some part of the USB driver. Other parts are not modified.
It would also be open source.

A non x24 design, interesting.
September 22, 2014, 12:39:47 AM
Do we have a CAD draft to see?
