Barring you posting up a whole list of the actual components that justifies it, I can't see how you'll ever get US$10k for this lot.
What 1200w single rail PSU did you fit into this math of yours? I don't know of a truly single rail 1200w PSU for less than $250

The unit has 8 PCIe cables and is rated for 98A on its 12V rail. Jonnyguru tested it at 91A, but it output 1200W at 86%+ efficiency.

The price I quoted was without the MIRs, BTW.
You can also get the OCZ ZX1250 for the same price, but it only has 6 PCIe cables so you'd have to use a couple double molex to 6pin adapters.
