RAID for what now?

So My plan with installing Panther Server on my old B&W G3 was to RAID the 2 9 GB drives on the 2940W card and create a nice fast system drive, with a cron nightly backup to a ATA drive. But I guess that unless you shell out the bucks for an Xserve, you can't startup off of a RAID created with Disk Utility... That's frustrating for me, especially since this is all Apple OEM gear... But the 4 port NIC does show up nicely... So is there a hack to enable booting off of a RAID in these machines (non-Xserve)? If not, what would all of you server mavens recommend that I use these nice LVD SCSI drives for? My last lonely slot in this machine is going to pick up my Ahard ATA card and my drives from my old beige box, so I have lots of HD space, and expansion room.... Theoretically I could put 2 drives on the (empty) motherboard ATA bus, 2 each on the 2 ATA busses on my Ahard card, and the 2 that are on the SCSI card....I could even probably cram one onto the IDE bus (No ZIP).... 9 drives.... Would I run out of power or space first? But that's just a theory. But what would you recommend? It's sitting by my desk now, not online yet, so I can do anything with it. Panther Server is running on it, and nicely. I'm about to go get the updates running on it... But I can always reinstall if the drive rearrangement justifies it... Thanks in advance.
