Case work update:
- Power distribution and control PCB expected to be completed by early next week. Will support both Raspberry Pi or Beaglebone Black.
- Mechanical design is essentially complete, just need to complete part drawings and fire off to Steamboat
Still no price estimate, as this will depend on the quantity of parts ordered.
Changes since last design:
- 15 K16s per enclosure necessitated by a space added for an ATX PSU
- Ethernet connector added which will allow direct connection to the Raspberry Pi or Beaglebone Black for standalone operation
- Power distribution and control PCB will have both Molex and terminal strip connections for power
Case design could easily be adapted to support other PCBs (i.e. Bitburners)

It's been a few days, and I was just curious if there were any more updates on the cases? With avalon starting to ship chips, I am very anxious to lock down how I am going to house and power my (16) boards. Timing and pricing are both important to me, but if I had to pick one, timing would be of the greatest concern right now. - Power distribution and control PCB expected to be completed by early next week.

Thanks in advance!
I know I am a bit late on this, but +1 on the case as well. Curious what the pricing would be, but given the PSU(s), cases, cabling, and time/effort involved, this seems like it would be a big win for those of us who bought more than a handful of boards.
Is there any update on if this is going to be offered (or what price it might be offered at)? Didn't see anything on http://liquidsyndesigns.com or further mention in the thread...

Case work is in progress. I received the first machined parts yesterday and am assembling prototypes. The PDU PCB design is underway, and I should have something to show next week. The Mineninja folks are on-board with development.
Some pictures from today:
Everyone, meet Jimrome. He is the creative talent behind the CAD drawings you may have seen on the front page of this thread and the website, as well as the project lead for our case.
Thanks for the update. Can't wait to hear about timing and pricing of the case. I hope we hear lots more from jimrome soon!
Re: [Ann] US based Avalon ASIC chips and assembly: 4,600 remaining
Update:
Hosting:
The switched PDUs and PSUs are arriving early next week. We have chosen 550watt 80+gold PSUs to give both high efficiency and fine grain control for power cycling boards should the need arise. Each PSU will power between 13 and 15 boards, depending on the final power usage. The PSU will then be connected to our switched PDUs, which gives us the ability to power cycle the PSU remotely. The network infrastructure and configuration is nearing completion, and we will be ready to receive the units once they are assembled.

Hi SB,
maybe you should consider revising your choice of the PSU or plan less boards per PSU.
According to the best practices you shouldn't run a PSU at more than 70%. So a 550W PSU would be most efficient running at 385W. 12 boards running at 32W each would consume 384W and with slight overclocking even 12 boards would push past the 70%.
+1 on the case. Is that 21 boards in there? I wonder what would it look like once you plug in all the cables.
Cheers
24 x K16s. Cabling should be neater than you'd think as the design is based around a central controller and power distribution unit PCB (CCPDU). Two wires will run to each of the "blades" (composed of 3 X K16s) where the wiring will then branch out to individual boards. So only 16 power wires running throughout the chassis.
Data comms are another thing, but the plan is to use an I2C chain terminating in a single USB connected K16, which will in turn be connected to a Beaglebone Black which will act as a controller and cgminer/bfgminer host.

Re: [Group Buy]12 KNCminer Jupiter's 15 Sold [Closed] Jupiter Pool
I took a look at Bitfunder, but am not that familiar with the details of listing shares of miners (specifically what the costs / caveats / issues are of being listed).
1. Are there additional costs associated with this? (Listing fees, mgmt fees, etc)
2. Are there any restrictions on shares? (Lockout timeframes, sale fees, who can buy/sell, etc)
3. How is EOL handled for the fund? (Yield < Power costs)
4. For a mining pool, how are hardware failures handled? (Direct dilution across the pool, specific person is SOL, share retirement, etc)
Sorry if these are elementary questions. I have experience with stock options (employee and "general"), RSUs, stocks, bonds, etc, but have never worked with something like this in the bitcoin space, and don't feel informed enough about it to vote "+1" or "-1".
Thoughts?

Hey guys,
1. I have offered to waive the listing fee for you guys, and there are no management fees.
2. None.
3. That is no different than how it is handled currently.
4. Also, same answer as how it is handled now.
BitFunder is just a means to be able to account for, and trade your shares.
Hope this helps
Ukyo
Ukyo, thanks for the details. I appreciate the patient responses on this!

Re: [Ann] US based Avalon ASIC chips and assembly: 2,779 remaining
Order #100000070 for 16 boards (my 256 chips are from batch 5).
Chose Full assembly + testing, and express mail shipping.
Now I just need to solve the case and power supply situation.
Steamboat, thanks for all the hard work on this!

Assembly and DIY kit.
I finally got the BTC together to do this. And just as I get ready to pay, sample chips come out. I will take this as a *good* sign (far from risk free, but good).

Re: I need to be able to post outside of Newbie (urgent), when or how can I do it?
From what I hear, the rule is 5 posts and 4 hours of browsing, but the rules don't spell that out (or at least I haven't found where they spell that out).
Good luck!
Good luck!
I totally agree that would be frustrating, but I think (at the end of the day) the amount of time you get "credited" for, between links, just might be a bit lower than you would like (aka session "timing out", from the perspective of "total time logged in").
At least as one who also wants out of newbie jail, I hope that is the case

Re: It's stupid that newbies must make 5 posts and browse for 4 hours. Here's why
I have been lurking in the forums for a while now, and I find that, overall, the quality of posts and discussion here are much better than the chum bucket of "open" forums.
The criteria might be arbitrary, but it is effectively the "price" you are paying to gain entrance into the discussion. If you don't value the forum at a level to make 5 posts in the newb area, and browse for 4 hours, than you are unwilling to pay the (arbitrary or otherwise) required "cost" to gain posting privileges.
Keeping forums clean is a tough job, and better some simple filters than moderators being overburdened or the discussion being swallowed by spammers.
