[ale] Prebuilt or assemble an off-site backup NAS box?

[rajaw at c64.us (Raj Wurttemberg)]

I am looking to provide an off-site disaster recovery storage server for one
of my clients. The box will be headless and run some flavor of Linux. They
are currently running a Netgear ReadyNAS NVX which I have "tweaked" to allow
SSH access (rsync works too). 

I priced out a new NAS from QNAP and it came out to about $1,100. I really
like the QNAP box, but as little as it will be used I think I could build a
small box and throw in some inexpensive SATA drives and get more bang for
the buck.

Thoughts? Comments?

Kind regards,
