Thanks you all for this discussion :)
I was looking at this kind of gear:
http://www.supermicro.nl/products/system/4u/7047/sys-7047gr-tprf.cfm
4x PCI-E 3.0 16x buses so enough bandwith for 4x GTX680.
The power supply in the 1600 W range should be enough
The 300W GTX690 are probably too much drain (both thermal and power)
and with the shared PCI-E bandwith issue, that's not really good! :D
I might go from lower CPU specs, 2 sockets at 4 cores instead of
the high end 6/8 cores.
Of course they will cost more than your spec'ed GPU dedicated boxes

I am trading space (4U rack/4 gpus) and remote management (ipmi/kvm).
Since this is for one proof of concept box before choosing
K10/K20 GTX680 or plain M2090 for a few more boxes.
I really enjoyed your [AMBER] Tesla or GTX? thread reply!
Best regards,
Tru
