For systems of that vintage, our recommendation is to use Linux
software RAID on disks attached to the onboard Adaptec SCSI
controllers (aic7xxx driver).  CentOS 4.4 can create software RAID
arrays at install time quite nicely.  I ran this config with Fedora on
my last PE2400 for several years before finally upgrading to newer hardware.
