If the new drive is an SATA drive you'll find it fits perfectly when you open the side of the G5. There are little power & SATA connectors tucked away underneath the drive bay. If the new drive doesn't match those connectors, and has instead a 40- pin connector like that at the back of the optical drive, then take it back to the shop & ask them to exchange it for an SATA one. It'll cost a few dollars more, but probably not as much as a PCI EIDE card that may not be supported under OS 10.7. Stroller.
