      Adding to that, at home I have an ancient Synology DS212j; I
have seen the newer comaparable models for a bit over $100 without
drives. Power-wise a RbP4 kicks its ass, but it has been shoving NFS
and iSCSI data in jumbo mode for my vm hosts for many years. It can
also do SMB and other stuff. And I tend to ssh into it to manage the
box instead of using the web interface. Why am I mentioning that
instead of a build-from-scratch solution? Wife factor: get it up and
running in half an hour and move onto something more interesting with
the pi.
