Yeppers...but why the crap is windows throwing me the warning now? Lemme check a couple other BCT notification links...nope, just clicked the Rockminer notification email link without the warning

hmmm, very strange, I clicked a link from an outdated (older) notification email for this thread an no warning. Ah well, not long before I start designing the enclosure for these boards!

We got our boards today and just wanted to pop some pics of our setup.  The boards work flawlessly as expected, and everything ended up excellent so far.  Those fans on the PSU are 60mm case fans and seem to be holding up well.  They are only 3-pin fans, but connect to the fan header just fine and so far provide enough airflow as we can tell.

We're doing "blocks" of 4 x S3's per PSU.  If it works out correctly, I believe we can get 4 "blocks" (16 miners) onto a single 30A 240V circuit.  This will give us much more density per rack than maxing out the PSU's with 6 S3's per.

We currently have 2 blocks wired and running stable for about 6 hours so far, will add the second block tomorrow and see what happens.

thanks for posting those pics. They will help with my enclosure development, woot!

Cool, glad it's helpful.  Once I get the other two blocks done tomorrow I might try to take a pic of the rack to show how we have that setup as well.

FYI we used the 18" cables on the top 2 S3's, and the 36" cables on the bottom.  Setting it up like that the 18" cables were _just_ short on the bottom ones, meaning there was now a lot of slack on the 36" cables.  As you can see we did some interesting cable routing to make it presentable and not have cable soup.

Pretty sexy there, sir.

Anyone with a pending order right now, my apologies that it hasn't been shipped out. As has been stated, PCBs were delayed a full nine days past expected delivery, which pushed manufacture back into time we had reserved for a custom job and the full week we were intending to shut down and move to the new shop. We'd hoped to get the rest of pendings out on Tuesday, but the cable parts we expected to have on Saturday just arrived today which meant our stock was basically gone last week and never refilled. We'll be completing the move by the end of Friday and the first order of business Monday morning is to blast out an aslo of DPS2K boards for every pending preorder to be shipped by Tuesday (if the new cable minion can keep the pace). As soon as we're up to stock on those we'll be shifting over to the new D750 batch and hopefully have some of those ready. We will also have two custom jobs to juggle next week but that shouldn't slow us down on pending orders since those take priority.

Just an update. Anything that hasn't shipped out yet should be shipped no later than the 19th. That is much later than originally expected but I can honestly say most of the reasons for it were outside our control. When we got everything we need (like last week) we lay down the law and get stuff done.

nice setup , what fans are you using?

Here's the pic of the box that the loaned DPS2kBB was shipped in...fortunately the board made it safely!






Anyways, I am working on the enclosure and will have a better ss ready soon!

masscool 60mm case fans, 3-pin.

 Looks real good! My question is why the zip ties on the fans, You could use sheet metal screws and washers to barely penetrate the psu case and silicone the edges to insure all air in, is in the psu not all over the place. Just a thought...

 If your worried about the screws touching, simply remove them after the silicone is sealed, they ain't going anywhere..

Honestly the zip ties were used for 2 main reasons - first: quick, dirty, cheap (not that screws and washers aren't) and what we have readily on hand (zip ties are never far in an IT shop).  Second we weren't sure about the permanency of those fans, so if we need to move/remove them it's a couple nips from the cutter and they're gone.  We weren't sure if the 60mm fans would provide enough cooling, if they were in the right spot, whether we needed to go up to 3 fans, or go bigger with 80mm (which we did today as a test on a new stack).  Believe me I'd prefer a much more permanent and clean solution, but this is our first proof of concept with this setup so zip ties just made it easier to start.  I could forsee either screws or a custom bracket in our future.

Alright, I am about to print the first prototype base plate...here's the screenshot I promised...
Once I get the base fitment correct I can start making the lid


Can anyone please supply me with the dimensions for the front/rear of the DPS2k PSU?  (just need the width)
Thanks!

I can measure this evening if no one else has by then.

Sweet, thanks! Make sure to measure the bottom please  



Also, I could use these measurements for a stronger, more secure mount as i would like to make the mount/enclosure screw onto the PSU...see pic for references. (edit- Distance from screw hole CENTERLINE to bottom of PSU) Thanks!


One last edit...I should have some pics of the base posted this afternoon.
I am printing the 3rd prototype now!

Does someone know the "customs tariff number" / "Zolltarifnummer" for importing the breakout board into EU / Germany?

Very! Thanks much. I will be getting back to work on this today. I've printed 4 prototypes thus far(getting close!)...oh yeah, gonna snap a couple pics and post those asap.

 Would you be interested in building a semi rack for a 2 stack? I will be stacking mine and using 120mm fans. I will need 10 of these. How tall can you print?

 Basically a 2 shelf system with 1 side cutout for the fans.

I could easily make them connect together with zip-ties or screws, or maybe design with a dovetail for adding or removing units with ease.
I'm thinking maybe a 2-PSU design with connectors for stacking more plus provisions for securing the units to a wall/shelving or whatever....they would (possibly) slide over the front and rear of the PSU and secure to the PSU with screws.

About to take pics of what I have so far...nothing spectacular (yet)  

Oh and my printer can handle 6x8x6 (xyz) rough build envelope
