Prototype mount for DPS2000BB server PSU (with breakout from http://www.price-technology.com).  The bracket leverages the 80mm fans for cooling the PSU and mounting the bracket to the case.   Cool







There is ~65mm of vertical height from where the motherboard would be to the bottom of the mount.

what holds the break out board steady?

could you photo the case form the outside showing the fans that would cool the cpu? tia

An M3 bolt will pass through the breakout board and an unthreaded spacer into a threaded hole in the extrusion.

Not much to see:

Nice work. I used those psus and breakout boards.

Looks good.  Using a low profile CoolerMaster CPU fan for an LGA 1150 or LGA 1151 build and that should be fine height-wise.  Also, a stock Ryzen fan should fit underneath the PSU with some room for clearance.

The other option would be to talk to SideHack or Price Technology and get the screw-in terminal type of break out board as that would help with top of the case clearance (You would not have to deal with the fixed height of the 6-pin plugs on the breakout board, so you could lift the PSU a tad higher, which ought to help with CPU fan cooling.  I think only Price Technology would have the screw-in board for the 2000BB available immediately, but SideHack could make them if there was enough interest.

But that would mean removing the top 'square' part of your frame that sits on top of the PSU.  Why not run at least one of the horizontal mounts all the way to the side of the case where it could be secured with a screw?  You could keep the vertical posts but cut to the same exact height as the PSU, but remove that extra not quite 1" from  the top square part and get that much more clearance for CPU/CPU fan cooling.

One other item you might want to check:  order a mini EVGA GTX 1050 card and adjust your height so that the mini 1050 GTX card fits in the main PCIe slot.  That gives you an easy-to-access HDMI port for when you need to connect a monitor to the rig, and it will mine a little bit as well.  The big gun cards then can all go up front and connect back to the motherboard via the USB cables/risers.

I think that layout as you have shown will handle the PSU cooling just fine.

The only other option that I can see is to house the PSU outside the main 4U case and run longer than normal power cables to the GPUs, risers, and PICO psu.

Nice work.

Last point:  The Lamptron CF525 5-fan controller can be mounted up towards the front (Left side as you face the back of the case).  Running fan cable extenders allows you to quickly connect up the 3 Delta 120mm fans up front and then the 2 80mm Deltas (or equivalent) in the back.  I've found that the cooling is fine even when you dial the fan speed/noise level down.

Estimated cost at this point?

One question:  What is the third leg holding the platform connected to?  I see the two main legs.  EDIT:  never mind, just figured out the "leveraged" part of your description.

This is cool.  I can't wait to see what it looks like with GPUs and some thermal profiles! ;-)

This is the safest implementation of the breakout board I have seen from a grounding perspective as well.  Everything is coupled to chassis.

Nice work

Great design - I've tried a couple locations around those Rosewell cases, but none I was really satisfied with.  Love the idea of using the 80mm fans to help cool the PSU, and I'm assuming you're screwing into some of the spots on the bottom of the the PSU to hold it in place?

I'd love to see a shot of it without the PSU in it, so I could get an idea of attachment points, plus then look at my existing cases and see what the cable clearances are, etc.  Overall I think it's an excellent solution for the problem - what are you thinking the cost will be?
