If you can slide a disc drive into place from the front of your computer, then there won't be any diffculty in doing this step last. There will probably be a protective cover which you will need to punch out (you may have done this during step two). Also, most disc drives are held in place with screws. Hopefully you purchased a SATA disc drive - as opposed to the IDE interface - to make your life a little bit easier. Just plug it in and power it the exact same way as a SATA hard drive.
