I have a custom built PC for myself and I accidentally ordered a CD/DVD READER and not a writer. My old computer which was a DELL Vostro has a DVD/CD Writer & Reader. Would it be possible for me to take the DVD/CD Write & Reader out of my Vostro and add just add it to my custom built PC?

Would it cause any complications? (The Vostro Reader/Writer is the one that came with the computer when I bought it)

I don't want any harm done to my motherboard by adding this one.

Please let me know asap.
IT has SATA and SATA Power. The connections are fine and everything such as those are fine. And I do have Windows 7, so I guess I should make the swap?
