 ah it's not all parts.

* CPU core: 1.25V @ 1.6A (so, want less power just run the CPU at a
slower speed)
* CPU internal logic (DLL, USB, SATA): 1.2V @ 1.2A
* DDR3: 1.5V @ 1A
* NAND: 3.3V @ 1A

those are the major bits.

 yes i know.

 well if you're doing your own motherboard, you could provide cooling:
that's not a problem.
