Hi John,
no matter how much RAM you have, you still need hard disks for the cache
volume.
Just follow Novell recommandation when making your NWFS cache volume (no
more than 8GB per volume, no compression,...).
BM Proxy Cache doesn't need fault tolerance, so your hard disk IDE seems
fine to me.

Regards, Fabrice.
