Can I set mirror drives with no RAID in a Linux environment?

I have a OptiPlex GX520 with (2) 80 GB SATA drives. I am going to install CentOS. I want to have the drives mirror but the box has no RAID. Can this be accomplished? Is there a way to mirror the drives before I install the OS?

Thanks in advance.

I am not familiar with the CentOS you reference, but you would need to see whether software raid is available through that distribution.  I.e. during the installation process when you might be asked to select the drive for the OS install and partition it, there might be an option for RAID where you can either group the two disks together or group partitions together.
The following has links that you might find helpful: http://www.centos.org/modules/smartfaq/faq.php?faqid=47

Add a Raid card and configure the array through the card's bios, but you'd need to be sure the card supports that OS.
