A well built NAS will save many hours of grief if built right by protecting 
data integrity.  Just remember it is not a backup.  The important things are to 
use drives made to operate in RAIDed configurations as those which are not may 
experience enough errors to get dropped.

NAS4free appears similar to FreeNAS - supports ZFS.   I would recommend using a 
minimum of 4 drives in a RAIDZ-2.

ZFS likes memory and you would want a minimum of 4GB of ram to get by (note: 
recommended is 8GB). If could manage it ECC should also be used for memory.

If done right will be bullet proof - excluding hardware failures, power surges 
or lightening.

I spent a decent penny for my build but it wasn't done simply to fulfil a need. 
 It was relevant to the type of work I would be doing - supporting storage 
environments.

We could talk more in depth if desired.  It need not be expensive to build.  I 
was tossing out 500GB Hitachi RAID capable drives recently.  Just couldn;t sell 
them... :(

Take care,

Matt
