Say if the mobo is messed up. Could i just swap the hard drives and ATA pci card over to new mobo and wil that just work?
If it's a similar mobo, yes. Don't know what happens if it's a different chipset. Could work, maybe not. Personally, when I'm going to use a new server/hardware, I let the installation procedure figure out what hardware I have and have it install the appropriate drivers.... You could try, depends on how important your current server/data is and if you need to keep it online as much as possible. Make a backup 1st and test your restore.
