Suggestions on RAID Card

[greyhair <greyhair greyhair net>]

I'm looking for raid card suggestions for a RHEL 4 server.  I would like 
to use *Real Hardware* RAID (Raid 5).  I was hoping that 3ware or 
adaptec would be choices but I do not see RHEL 4 support.  Also, I would 
like to run A sata hard drive, dual opteron system.  I'm building my own 
for I do not have the money to buy one.

Any help would be appreciated. Thanks
