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.
