Get new SATA drives. Think about this, your hard drive is the slowest piece of hardware in your system, by a mile. Now, if you are running new hardware to point that it no longer even has PATA ports, why in the world would you want to cripple the performance of your system by using that old ATA drive? If budget limited, I understand, but you can get a new SATA drives for reasonable prices, and though its not too big of a deal, you don't have to deal with old big ribbon cables and jumpers, worry about master, slave, cable select, etc. The BIOS takes care of what drive does what, and the boot order.
