You'll only need to buy a caddy if you're going to stick it in the DVD drive slot. Otherwise, the 2nd HDD section actually has a caddy there.
You should be able to order a caddy from the upgrade options if it's still available for your laptop.Wondering the same thing. Bought an SSD which I am currently using instead of the HDD that came with my 17.3" Optimus II and want to replace the DVD drive with the HDD that was originally in the laptop.

Under DVD/drive select HDD optical bay caddy,and under "installation service" select "not required-I will complete upgrade myself".
