Does someone have a Netapp-approved list of components that can be used with the F210 and F230 filers without voiding service and support warranties?

I bought a minimally configured F220 a few months ago, and populated with third-party RAM from Kingston, Seagate Barracuda 4.3GB narrow SCSI drives, and DEC StorageWorks canisters. The total cost came out to 30% less than an identical system put together by Netapp. The new filers use fast/wide drives (I heard that Fujitsu drives are now on the approved list) and a different canister (metal instead of plastic, for one thing). Does anyone have vendor and part numbers for those components? Much as I love Netapp, I still find the pricing a wee bit steep. ;-)
