Some observations from drives I have handy:
*  The two Lite-On DVD burners laying around here don't eject fully.
*  An older Toshiba/Samsung (TSST) drive, TS-H552U, might work.  It's really 
close though.  You can place the disc in the tray for sure, but if the disc were 

to be slid a little forward in the tray during removal, it might be a few mm shy 

of clearing the front bezel.
*  The old Toshiba CD-ROMs and DVD-ROMs that Sun used eject fully.  My SunBlade 
2000 has the SD-M1401, but it's SCSI; find the IDE equivalent of that generation 

and you should be fine.
*  If you are looking through the closet for drives more likely to eject fully, 
without looking for a specific model, I'd probably stay away from the 
short-depth drives that most manufacturers are putting out these days.  An 
older, full-depth drive is more likely to work.  The full-depth types are 
approx. 1.5" longer than the short ones.

good luck,
