Raid card, for backup/entertainment system

[lerninlinux at comcast.net]

Besides the norrmal surfing/email, etc type stuff, I mostly use the computer to listen to my music (rather then swapping cd's).  So I have been looking at the Low Power gOS motherboard (like in the Walmart gOS pc), as a low power music/backup system.

Since it is low power, and my plan is to leave it on, I have been wanting to make it my NAS/Backup box, but I need to find either a SATA (preferable), or PATA, pci raid card.  Any suggestions?

Thanks
