I use this with NetBSD:

https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/open-source-hardware

It has even a SATA port (but you can only power a 2.5" disk since it
provides only 5V power; if you want a 3.5" you need probably an
enclosure with power supply).

The board takes 5V and consums up to 0.650A; if you add USB devices
(2.0), you can add, at worst, 0.5A per device.

I use it for a GIS server, with low trafic, and since it is mainly
vectorial stuff, only an USB key as storage with some tens of GB is
needed. I have just made these days the computation of the energy
needed (with the configuration, the programming and its use for now:
mainly it processes files on a daily basis to update maps and
databases, producing even xlsx files, but via a cron job called once
at end of working day) and it consumes only 30kWh / year...
