[kwlug-disc] The sweet(?) smell of power supplies

OK.  What amount of disk capacity are we talking about? Anything up to
1TB can be done today for a reasonable amount of coin on SSD.
What are the interfaces for specialized hardware?  PCIe? Interface count?

I suspect you can build a remarkably fast system inside of 150W with a
bit of research.  Intel E3-series v3 Xeons/Haswell CPUs pack a pile of
performance into 60-80W - at a decent price.  Especially if the software
uses recent instruction extensions eg AVX.
