I've got a NetGear ReadyNas Pro with 6 drive bays each containing a 2Tb seagate low power drive for 12Tb of usable space. It allows me to rip dvds in pretty much raw form to the nas and then transcode them (using
http://handbrake.fr) to whatever format I want. My wife wants to watch some RomCom on her phone/android tablet during a long plane ride? No problem! Get it at RedBox for $1.20, rip it, and transcode it to the proper size and format. The resulting file is only 300-450Mb, so her phone and tablet can hold gobs of them. Also, netgear has some pretty decent forums.
As a Linux guy, massive bonus points that the ReadyNas boxes are just modified Debian and they will let you get root on them. http://www.readynas.com/forum
I'm a HUGE fan. You can get a diskless 6 drive bay one for:

It is also a great time machine backup for my wife's crackbook pro lappy.
