ARM-based low-power server

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I'm looking for an ARM-based board to serve as a low-power server.
My venerable SparcStation 10 has been doing this flawlessly for some ten years,
but draining some 80 Watts of power makes me feel uncomfortable.

I would need Ethernet, mass storage (SATA), and a RS-232 port or USB.

There seems to be a wealth of boards like the Seagate FreeAgent DockStor, the
Raspberry Pi, Android-PC and variuos *Plugs---if I would like to use PenguinOS.
However, I would like to stay with what I'm used to. So, has NetBSD bee ported
to any of these boards? Are there NAS appliances or such known to run NetBSD?
