Partly because of a multi-point failure of finances (deposit computer errors and slow/non-paying customers) we were delayed about two weeks on ordering materials for the next batch of DPS2K boards. The next round should be available starting in about 4 weeks. We'll open up a (pre)order queue probably sometime next week once we have a better idea of when we'll be shipping.

Shipped a batch of DPS2kBB PSU breakout board bases to MinerSource.net just yesterday!
I will be test printing these racks asap. Stay tuned

Just a quick peek at what I am working on for these PSU modular "racks"

are you overclocking your antminers ?
maybe im pushing the PSU too hard running it at 2000watt constantly.
The S1's are overclocked to 393/400. But still I'm only running 4 per PSU so at most I'm pushing 1600watt, most likely closer to 1500. maybe im pushing the PSU too hard running it at 2000watt constantly.

Ninetoe - those look really good! And you're welcome, I'm happy it's working the same way for someone else... you never know when you make a suggestion if it's gonna work for someone or if it fails and you look like an idiot... 
I promised pics of mine with the new fan setup, so see below. I am also going to make a second post about the breakout board holder, as I got my shipment in and have a few comments.
I'll also confirm power draw. With my "cube" setup of 4 Ants per PSU, I am able to get 4 cubes per 30A 240v circuit to run reliably and cool. This allows me to get max density of 32 Ants per standard 19" rack cabinet, with only 2 circuits per cabinet. And, the S1's are overclocked to 393/400 as well so it's still able to hold just fine.
Here's a finished "cube" with the fans on the right side, set to pull air through:

here is my setup (top psu still missing 4 antminers on the way)

5 antminer running OC 250 seem to be drawing about 2050watt from the wall.
also the fans im using, on pull instead of push worked miracles, i run them at half speed and the psu is not warm to the touch anymore.
the type i used is a few posts back.
ty for the fan tips kgb2mining

on what side of the psu did you put the fans to pull out ?
ill soon be recieving my high cfm 40mm fans and would like to try the air pull method
I'll snap a pic or two today.

I had one PSU keep popping off , and I only run 4 Ants on any of them. Felt really hot - it was cooled at the time with 2x80mm fans. Swapped those out for 3x60mm fans, configured to pull air out, instead of trying to force air through. Been running like a rock ever since.
I've had extremely good luck with the 3x60mm fans configuration, and would recommend you try that. If you want to render your fans useless later on, you can clip the connector end off of it and put the wires directly onto the breakout board terminals (as long as fans are 12v), instead of worrying about the headers off the board. I can snap pics tomorrow if you want.

ok , i had the fans blowing in towards the psu. ive been looking at he 60mm there are some high speed ones at 4500rpm, im going to give it a go i think and do your suction technique, i snipped the current fans also as 2 wouldnt fit in the pwm pins.

I had three identical setups of 5x AM Tubes across 2x DPS2K. On each I put a lightweight 120mm fan (12V 0.5A 3-wire) and a sturdy 120mm fan (12V 3.3A 4-wire) to keep them cool. Two of the setups are running fine on probably around 60% speed on the sturdy fan. The third setup, one PSU kept cutting out even with two sturdy fans at 100% so I junked it and swapped in a fresh PSU, which has been performing beautifully.
Used equipment has varying tolerances on what it can handle, I guess.

yes used equipment is used equipment but 2 in a matter of days I thought I might be doing something wrong, they do get hot I think it must be the fans they are just not up to the job, I didnt know the board comes with the pwm fan pins. The fans I used seemed slow to me I will have to change them I reckon even though it said a minimum of 25cfm on their description but for 3quid what should I expect.

just got the boards a couple of days ago and had 4 psu's waiting which I got of ebay now 2 of the psu popped yesterday don't know why the boats are ok as use the remaining psu and seems to be running ok I have 2 of the following fans on each psu http://www.overclockers.co.uk/showproduct.php?prodid=FG-038-SV&groupid=701&catid=2331&subcat=819
had 6 ants on each psu , what could be the problem?

Probably not enough CFM. These PSUs can be really heat touchy.

So, will this work with a DPS-1600BB? Pinouts look the same, and since I'm running only 4 Ants per PSU I'd be fine within the wattage requirements.
yes that will work
Those would fit perfect since the case of the PSU is 105mm: http://www.ebay.de/itm/Arctic-Cooling-Arctic-F9-92mm-PC-Computer-Gehauselufter-1800rpm-43cfm-/360945537772?pt=DE_Computing_Geh%C3%A4usel%C3%BCfter&hash=item540a07d2ec
Does the 3 Pin connector work with the board ?

Would'nt it be bether/more efficient to place the fan's ON TOP of the PSU ??
Of course, one would have to cut some holes into the metal cover ....
But I think for cooling it would be more efficient.

You could try.
I also thought about that option but the heatsinks are positioned for airflow from the side.
