Make shure that:
a) you will be able to can get this disks over the next year, if you will have
    to restore a broken disk, e.g.
b) buy 3 + 1 disk, +1 as spare disk. 
     It's always good to have your repair kit filed up propperly _before_ you
     will need it.

So I would recommend a raid5 System with 5 Disks. A rebuild wil be a lot 
faster and its more robust than a 3disk raid5

You know that some hardware vendors offer special conditions for shools and 
So do HP and SUN, AFAIK. IBM and others might have the same conditions.
And even IPC Vortex did so in the past.

If you think about a standalone nfs server you should think about afs instead 
of nfs
