Ken, you can still buy add-on PATA (IDE) cards to stick in an expansion slot so you can use your old drives, and most new mobos still have an IDE connector on them as SATA CD/DVD drives have been a bit thin on the ground until recently.
Generally these IDE cards need the old style PCI slot but there are a few which fit into the newer PCI-e slot (as long as you have a spare slot!!)
