Any design ideas are very welcome!

In my experience with KNC's 28nm hardware, the primary thing stopping overclocking/better performance, was heat management. The best solution was to make sure the underside of the board is cooled as well... even just placing a high speed fan on the bottom of the boards worked wonders. I suspect that the neptune will be harder to overclock (the female pci-e connector and VRM's seem pushed hard on normal clock speeds, for one), but having some sort of mounting solution to better cool the top and bottom of the board might be a good place to start. You could do this by having the metal sheet that you mount it raised slightly, and place vents underneath the boards (or cut little asic sized holes) to give room for some high powered fans on the bottom. An even better idea might be to mount the boards upside down, and give a place to mount fans on the top of the sheet, with holes in the sheet to allow air to go through.

If one were watercooling these boards, I suspect that mounting them on their side might work really well also. That way you could put, say, a nepton 280L on the top side of the board, and have a high powered air cooling solution on the other side/both sides to keep the VRM's and that PCI-e port cool.

Just some thoughts...

Probably more rigorous DIY is needed by replacing the whole metal-plate (and fasten the Tower in a different way).

I would probably go back to the old mounting method for the heatsink plus separate VRM heatsinks, I suspect that will provide a better setup since you can get better contact with the individual VRM heatsinks.

Yes that is the idea... and some additional Fan's as well.

if you're serious about mounting the radiator the old way (turn the radiator 90^o, using the long bar/plate) and mounted using the two holes (the one to the right of the 10 pin and the other on the opposite side of the ASIC) - depending on which radiator they used as well, I've got the hardware to do it..

  I still have some of the plates, etc. to put it all together (similar to what I put together for the "Super Jup").
  I'm also working on a base/mount that you can put all the boards on (similar to the Jupiter)

  Any design ideas are very welcome!

I'm interested, I saw your work for the "Super Jup" and it was impressive! Are you thinking of something where we remove the Neptunes from their cubes and mount them on your base, plus associated plates and pieces? Or, are you going even further and thinking of a rackmount unit of some kind Shocked

I was thinking along the lines of a base with the boards mounted (5) five abreast, mounted using risers at the corners (10mm - 20mm) to keep the boards higher up to allow airflow underneath. As well, utilizing the plate and spacers (if an Arctic radiator), to get that brick off the VRMs.

Just a thought ...

i also fell for the hash while you wait "order conversion," but contacted KNC and they have put me back on the 2-for-1 Neptune list.

Now just waiting for shipment.. I'm a batch 0 customer and order still shows paid.

I doubled up all my pcie connectors by cutting and adding a molex or sata

The frankenJupiter ty-wrap method....
should be fine if your not shipping it....
