Preinstalling Office 2003 on an Image

We have purchased about 20 new PC’s with 20 copies of Microsoft Basic Edition 2003. My problem is how to create an image that has this Office installed but also overcoming the problem of product activation and licensing. I know you can do this for Windows XP using sysprep but how would you go about doing this for Office 2003. Will I have to leave Office out of the image and install it manually for all the PC’s?
