Do you have the thermal flow diagram (or the equations) for ventilation?
I had this same debate with BFL about 3-4 months ago, where I stated there were several problems with the case specifically air flow and thermal loss. They weren't addressed and look at the problems now... If you need someone to run the equations I'd only be too willing to help.
Nope, dont have this, for this prototypes i cant change anything anymore, but Iam very open to your support for a finsihed design with a possible reselling partner! Thanks man Foofighter

Thanks man Foofighter @kelticfox can you post what you found on the BFL case designs so we can see your take on the airflow and thermal loss? Would be nice to know Thanks

Hey guys, Unfortunatly I can not delivery the cases by this week, the manufacturer sent the cases a bit late and I will probably get them tomorrow evening or on Thursday. But I will be on vacation from 29-1 Sept. All parts for assembly are prepared now and at hand besides of the RJ45 connector. Worst case is, if i didnt get it until next week i have to ship without it. This means, estimated shipping will be, beginning to mid of next week (week 36). Currently 3 cases are left for sale.Meanwhile i added some more pics here: https://bitcointalk.org/index.php?topic=255737.msg2981262#msg2981262BR Foofighter

Hi, thanks for the info. I forgot to mention that, but I changed things a bit so a direct mounting of the Rasperry to mboard is possible. I will test every case before shipping, so everything will fit fine! BR Foofighter

Hi guys, sorry for the few news lately, work is in progress - see pic. But there are some issues which I have to solve first and rework some stuff by hand. Will come back to you with a more detailed updated when I have a bit more time. Regards Foofighter

Hi guys, I will take the time to tell you about the problems. First I thought I could usw sheet metal screws to fix most of the stuff, but this aint working because of painting thickness and other issues. Now I have to cut a thread manually in every hole in case and mounting brackets to fix this. The next thing was the Raspi mounting. as the Mboard was changed shortly before I ordered i had not really time to adapt everything. If the Raspi will be mounted directly on the new mboard , the RJ45 connector will push on the edge of the 3rd fan but it will just work fine. As I was not satisfied with this, I reactivated the bottom mounting holes of the case and now mounted the Raspi on the bottom connected to mboard via gpia with adapter Pins. Here are pics of first full assembled case, ready for shipping: BR Foofighter EDIT: Only 1 case left to sell!

Hey guys, The last days/week I really worked every spare hour sometime till in the morning, because of reworking the cases and stuff. Iam happy to tell you that all cases will be shipped on Monday, you will get the tracking number via PN on same day. Now to the bad News guys: As you know in designing the Case I considered primarily the old mboard, the only change I made is hole alignment on bottom to fit both mboards. The big Problem is that the Raspi looks in the wrong direction when mounted directly on the new mboard to the Fans. For this I made also Raspi mounting holes on the bottom and got some GPIO cable with adapters to connect to the mboard without problems, but somehow the Miner doesnt run with the GPIO cables. see here how it was supposed to work: It is still possible to attach the Raspi directly onto the board but this front plate will be bend to the outside slithly. see in my setup here. Sorry for the inconviniece guys, I tried everything -maybe my gpio cable is broken and the ones I packed for you are ok. I hope this is alright for you guys. Current projects if you are interested is an Shash board Case.regards Foofighter

sounds like EMI interference along the lines. This may be a good reference/example of the issue: http://www.overclock.net/t/1424387/gallery-build-log-ultimate-wall-mount-rig-maxxplanck-v2-completedGuy build a dead-sexy wall-mounted coputer system and used pci extension cables. basic cables caused his GPUs to not turn on. aluminum foil-shielded cables enabled the cards to run, but disconnect under 3D applications. He resorted to professional shielded cables for a working result try wrapping it in aluminum, or using a shorter cable. Your image shows that it folds over itself a bit because it is ~4inches too long, and this could be enough to cause interference

Try making the flat cable much shorter. It might be too long, just picking up noise. And do you have a seprate thread on the S-HASH casing? Highly interested:) intron

Highly interested:) intron As far as V1 M Board the default cable would normally work. However the problem is the orientation of the connections. One end of the cable will have pin 1 row connect to pin 2 row and pin 2 row will connect to pin 1 row. Thats not good You have to modify one end of the cable to make pin 1 /row attach correctly. Original Cable. Cable reworked.
