Yep, you are right. It uses the GPIO connector/header.

my first impressions/thoughts:
4) including a cutout or two for status LEDs or even a LCD would be cool. (I dont know if bitfury designed either of these into its hardware, but surely the RPi software can be modified to output status indicators)

Hi,
have already thought about that but there is no airflow just a heat accumulation, As i have to remove the rear Fans, and then only the front fans are left.

No, the width of the M-board is much narrower than the H-board. (about 1/2 IIRC). This would provide more than enough airflow to get to the exhaust fans without any back-pressure.
my first impressions/thoughts:
1) ditch the cutout labelling. as it was mentioned, it may make these more identifiable to thieves (as if a big humming box isnt already) and may cause the airflow to be wonky, creating random circulation paths that counteract the fans and/or lead to more noisy fan rotation. A sticker/decal is equally functional and more appropriate
2) I dig the rubber feet. Without them this could be a source of vibrations from the spinning fans and sound terrible as your big hashing box vibrates against the table endlessly.
3) I like the simple design. The more basic the shape/materials, the more easily it can be replicated by anyone with connections to a CNC or laser/water cutter and generic hardware.
4) including a cutout or two for status LEDs or even a LCD would be cool. (I dont know if bitfury designed either of these into its hardware, but surely the RPi software can be modified to output status indicators)
5) A modified case that is simply a backplane might be nice for those who simply want to mount thier hardware to a surface but dont want a full case necessarily (as mentioned in #1, a simple backplane with mounting holes for the psu/Mboard/Hboards would be cheap and easy to source from local cnc/watercutting shops)

My 2 bits -
I need something to house this damn thing in so it might as well be this. I have no special requirements for space. Have my own business and I'm just going to keep it in an empty office.
The only thing I would say is that I prefer the best ventilation / airflow possible. I'm in Arizona, nuff said. Also, if they do decide to replace these down the road with over clocked boards then I would like to be able to use the same case.

You can do 3U if you do the following:
Rotate the setup 90 degrees so that the M-board is towards the BACK of the chassis. This will reduce the height to 3U, and will not affect cooling at all since each H-board is in the neighborhood of 25W total heat production.
You might even be able to mount the RasPi to the back of the M-board doing this and save a little real-estate on the back side.
PSUs - server PSUs are longer and thinner, so you could use one of those instead and possibly cut some more space down.
Here is one example:
http://www.neweggbusiness.com/Product/Product.aspx?Item=9B-17-377-042
In regards to mounting, you can go simple and just have "rack ears" or if you want something on slidable rails, you can set that up as well. Rails = added cost, however. And I don't think this will weigh enough to really matter if it is just mounted by 4 bolts through a standard cabinet retainer.

Hi,

About the raspi, maybe in the future the raspi is directly mountet on the mboard as showed by tytus without taking more space.
Ok so i leave the rack ears as they are, there are only 10 holes because I reduced the height of the housing und so the rack ears are only 170mm in height but das shouldnt be a problem.
Iam not very comfortable with your suggestion, please correct me if i got something wrong.

This may seem paranoid, but I would suggest removing the "Bitfury 400GH Miner" marking from the case. If you're going to host this with a third party then you may not want to advertise to the world its intended function/purpose.
If had to check anyway how expensive this label would be in production, and i thought we can alternatively use a sticker for it, so everyone can decide if he would like to use it or not ;P
Overclocking on these boards cannot simply be "enabled" There is no magical toggle or switch. You have to physically modify the boards. Future revisions may have overclocking capability but as far as I'm aware the first batch will not be overclockable.
True.

Hey guys,
here is the Rack housing design, Cover will come a bit later.
19" - 4HE - lengh is 350mm
Iam open for your feedback.
One problem that came up, is that the standoffs for the M-board are to long and they stickout by 5mm on the ground of the casing. So i just reduced the height of the casing by 5mm because this seemed easier then making a second higher floor inside the housing(+ cheaper).
But is that a problem at mounting? Does the mounting rack lie on a guidance or something or is it only mounted and holded by the lashes on the sides of the casing?
Also I noticed there is a moveable gudance system für rack units, and a few racks on the market provide pre bored mounting holes for this matter, but I dont know the distances and hole dimensions and cant find any infos on that matter. Is this a must to have these holes at the sites of the housing?
regards

Is that design 3U or 4U high? In a datacenter every U costs you money ($50-100/mo per U for a GOOD datacenter with on-site security, etc.).
The holes in the rack are of standard spacing as well (3 per 1U), so you will need to make sure those line up on your chassis design.
I would also recommend that if you have 3 intake fans, that you have 3 exhaust fans as well. Otherwise those cards on the end without an exhaust fan behind them will have higher average temperatures. For now this doesn't matter, but if Bitfury enables overclocking on these boards for higher GH/s rates, this will become more important.
Thanks for the work, your design is coming along nicely.

I would really suggest to make a rack mountable case. Anyone who wants to stack them should buy a 19" rack.
There are small ones available too, like this 7HE.
I think the easiest way is to start building the case with something like that (already posted above):
Just get a front and bottom plate and you are done. Cheap and perfect for racks.

The original idea was to position the RasPI like this: http://imgur.com/TegDpOQ but we have problems to get connectors that are high enough above the board. To operate the board we rotated the connector and connected RasPI in an awkward way (http://imgur.com/jV1iis9). We will fix this later but even if You decide to use cables it would be better to reserve more space in front of the M-board for the RasPI.
=> put the fans on the opposite side.

Hey,
current distance from mboard to PSU is about 132mm, the rPI in the design has the measurments with rPI housing. Do you think 132 is enough?
Why put the fans on opposite side?

Do you have any idea when you'll have a finalized design? Also how much would you sell each case for?
I will take suggestions the whole coming week and implement them und then the design should be final.
The idea was that i would talk to some reseller( like punin or buzzdave), and he would sell the housings, my intention was essentialy to make only the design, but i think i will also make prototypes of it.
It looks pretty nice. Is the rPI fastened down somehow? How about clips for the fan wiring? Is h-board plug 0 on the rPI side? What’s the reason for the lip on the top facing outward? If that lip faced inwards then it looks like the cases could be stacked on top of another. Why do you have an RJ45 plug on the top rather than just routing the Ethernet cable to the rPI directly? I figure that would be one of the advantages of having an open case.
And most important… Any estimate on how much a case like that would cost?
/cet

rpi hast no mounting so far atm, will propably add mounting holes and put in standoff spacers like with the mboard, Yes plug 0 is on the rPI side.
The reason for the lip is for easier transportation.
Is anybody really going to stack these housings?
RJ45 plug is mostly for cord grip reasons and in my opinion it looks better this way.
The reason for an open housing are as mentioned cost reasons, because i think the sheet metal could get really expansive.
No costing estimations so far, I will implement the wishes and changes you suggest and should latest by the end of the weeks send out the drawings to sheet metal manufacturers. So i could probably get an offer in week 29.
