[ale] DIY NAS vs Boxed NAS?

[agcarver+ale at acarver.net (Alex Carver)]

I'm making a plan for some major network and hardware updates over the
next year at home.  One of the things on the list has been a large-ish
NAS box for storing backup images of the various computers, recording
video from IP security cameras, and possibly just having a small shared
area for files that need to be shared among multiple computers and users.

Given the proliferation of various boxed NAS devices like Synology,
QNAP, etc. I wanted to find out what other people would consider doing,
whether they'd just get a boxed device or put together one from a
motherboard, some SATA cards and a case.



One other thing: what file system would you put on top of the array?
EXT4, Brtfs, something else?
