Heya Silver, long time bro!
I've been following your thread here, just now finding time to reply.....
I have a home server that also has an attached NAS with 4 HD setup, both are Linux based and both I'm able to connect to while I am out anywhere from home via secured login
I was going to post this link:
http://www.freenas.org/ for you to go check out
my server setup lets me to allow my Daughters, Sister and her daughters to login remotely ( from Hawaii, Florida, Tenn, Kentucky, etc...) and access all my music and movies, etc... and stream them...even do back ups of their own computer systems, etc...) ... maybe similar to what people call a "Cloud" type thing...
whether you go the home Server route or the NAS route ( or even combine the 2 ).... I recommend using Linux for your OS for either or both....
hope this helps
TC / Johnny
