I know the Unibody MBP's require the SATA connection if you are trying to put a second harddrive in the optical bay.

I purchasedTHIS one.
 
yes, but I had heard that the non-unbodies have PATA, and since it would be a pain to open up the comp just to check, i was looking to see if anyone with my model had a confirmed answer
 
I did not know that. Yeah the pre-unibody Pro's were definitely a pain in the ass to open up.

Hopefully someone will chime in with the correct answer.
