5W per card in the current standard, with an "option" to increase
that to 10W *if the housing supports it*. that means having

no ethernet. USB3 *if the Card supports it*... which the A20 doesn't.

you can't get a 1000 pin 15W *processor* nor can you get 128-bit-wide
DDR3 memory bus bandwidth into an EOMA68 case. ok the latter you
might be able to do if you used 4x 32-bit-wide LPDDR3 RAM ICs but the
entire 5W power budget would be blown on running the RAM even at only
