Actually, they are different names for basically the same thing -- lots of
harddisks that can be mounted over the net.  NAS is a dedicated NFS server,
so there is no need for DNS, Sendmail, Apache, IPtables, etc.  

For IDE solution, 8 x 120GB is ideal because you can use 2 channels from
the motherboard and 6 channels from Promise card.  If backup is not of an
issue, then you can put 2 disks on the same IDE channels and you only need
4 IDE channels.  For SCSI solution, multiply the cost by 4x. :-)
