I was thinking DAS was not a good option.  It seems like a feature
removed and cheaper version of NAS. 

I think I've seen a couple Synology NAS boxes but I think even used they
were a bit pricey.  Still, used could make that a option.  Maybe.  It
could fall into the category of pay a little more for a much better
option, even if it is used. 

I've considered using older systems I have for NAS but they are large. 
Way to large.  It would require a lot of effort to shrink them down if
it is even possible.  A NAS is smaller and designed for what I need as
well.  This is what I found that goes with the Raspberry Pi.

There is a two bay and a four bay version.  I think the case is the same
for both so I may go with four for future expansion.  Price isn't bad
for that part but as you say, Raspberry Pi board is a bit pricey.  Thing
is, given the amount of control I'd have over it, it could be a better
option long term.  I might add, I think this board is somewhat new.  I
meant to include a link to it but forget.  It could be that you are not
aware of that, or many other people either.  Also, I'd like to buy it
from a more local vendor.  I've bought things from China through Ebay
but it has a guarantee and refund option that is fairly good.  It's a
option I've had to exercise a time or two. 

Part of me wants to buy a used but well featured NAS box.  Part of me
thinks a Raspberry would be better and have upgrade options in the
future as well.  I'm pretty sure I could have encryption on a Raspberry
NAS as well.  I'm not sure if a prebuilt NAS box has encryption or not. 

Hope for some good ideas tho.  I'd like to avoid buying something that
won't come close to serving even current needs or just plain doesn't work.
