Since I did a similar mod, I would recommend you put the HD in the HDD's place, not the optical drive bay. The HDD bay is designed for a disks that vibrate and get hot etc., while the optical bay is not. If your HDD is there, your keyboard will get uncomfortably warm if the HDD is used, and the whole case will vibrate. Put the SSD in the optical bay instead.
