Can I use my ruined Unibody MacBook for parts on an older Mac?

Hello,

I awoke this New Year's Day to find my 6-month-old, 13-inch MacBook Unibody A1278 sitting in water. The logic board is totally shot, but my hard drive, screen, keyboard, etc. are in tact. The drive is 250GB, and I was wondering if anyone could tell me if parts like the hard drive and screen from my ruined computer would be compatible with older MacBook models like the 13-inch white MacBook Intel Core 2 Duo/2.0 GHz.

I'm thinking about buying a certified pre-owned Macbook that only has an 80GB drive and marks on the screen from the keyboard. I want to know if I would be able to replace the screen and drive with the ones on my Unibody.

Thanks for any help. It would sure get this year off to a better start!
