Replacing Optical drive with HDD in MacBook White 2008

Hello everybody.

I have a Macbook White, NON unibody, bought in September 2008 (2.4GHz core 2 duo, 2GB DDR2 SD Ram)

I need to change some things because I need speed and much space inside my macbook.

I am thinking to replace the 160Gb HDD with an SSD.
AND, I want to know if in this model it's possible to replace the optical drive with an HDD of, let's say, 1Tb (or 1.5Tb).

I am searching the net (maybe I don't search the right way) and I am only finding tutorials and youtube videos about how to do it with unibody Macbooks.

Is it done the same way? Is it done in another way? Is it even possible to do that on my macbook?

Please let me know and thank you for your time.

Thanx for your quick answer!

I m searching for HDD of Western Digital and the best I get at 9.5mm are on the site: http://wdc.com/en/products/catalog/

The very first one on mobile category:WD blue 1Tb (WD10JPVT)
and the first one of WD black, 750Gb (WD7500BPKT)

I am a photographer and need much space for my photos (internally), as well as speed (for photoshop and programs like that), which one do you think should be more suitable?
