The "bare metal" restore most companies tote is not as seamless as
they lead to believe and often requires to be run on a "Server"
version of Windows.

I would follow Les' advice and use an imager program like clonezilla
or Ghost and make a quarterly image and put it to an external HD and
have a bootable USB memory stick or live CD with the software on it
to restore the image if necessary.

Ok for now, just get the cheap 3ware card you were planning as long
as it'll be supported in the future. Get an external HD and download
one of the free cloning packages live CDs. Clone your hardware
mirrored setup to the external HD. Have the OS backup software
perform nightly backups to the external HD.

Then you have some hardware fault tolerance, and backups, as well
as an image of your HD just in case and all for a lot cheaper
then when you were talking complete redundancy.

If your computer blows up, you can have another computer available,
wait you do, your CentOS box...
