Not sure if it would be a problem. I am currently playing with an
early eval board with a dual Cortex-A15 at 1.5GHz without a heatsink,
and running one full out as a buildd to experiment with. The other 10
miscelanious cores are idle at the moment, but over all I think it is
supposed to run at 2 or 3W, so that CPU there might only use 5 or 6W
running full out unless you actually decide you want to use the graphics,
which might take a bit more.
Of course the board I am playing with does have SATA and 1.5GB ram,
which I am very pleased with.

Yeah, best I have seen from eMMC so far was 28MB/s. Better than microSD
at 20MB/s, but not SATA.

It also looks like ethernet is connected via USB.
That and the lack of sata is just a typical problem with the CPUs designed
for use in a smartphone.
