Are the CD-ROM Drives in the Lombard the same as those in the iMac 233 (tray-load)?

From what I've seen, they look exactly the same, except for mounting hardware.

What I'm basically asking is, if the iMac drive is removed from the actual mount and swapped with the mount thing for the Lombard, will it work?

Let me know if I have to, and I'd be glad to clarify anything.
