I had a 3 disk raid 5 array running on my AthlonXP 1600 and the most I
ever saw it use under heavy load was 10%. I did once have to rebuild
the array after I stupidly killed the power to it during a large
write. That obviously took a while on the machine, which thankfully
didn't need to do anything else at the time.

So that should give you a good point. Also think of it this way, for
$300 you can buy a new mobo, Athlon64 and 1GB of RAM, which overall is
a better use of $300 in my opinion.
