Maybe this is what Janet Jackson had in mind
The SB75S hides a CD or DVD drive behind its swinging drive cover. This cover is hinged and tensioned, so that it opens when the optical drive trays slides out and closes when the tray slides closed again. The eject button on the front of the cover uses a simple lever mech to transfer pressure to the optical drive's actual eject button.


The optical drive cover is pushed open when the drive tray opens


Note the sliding plastic tab for the eject mechanism

This is a slick little design, but it will naturally work better with some drives than others. The button-pusher-thingy slides left and right within a certain range, but drives with odd button placement may not work quite right. Also, slot-loading CD drives need not apply here.

I used the SB75S with a couple of optical drives, an Asus 52X CD-ROM drive and a Pioneer DVD drive. Both worked with this mech, but the Pioneer clearly worked better. Once or twice, the Asus drive tray got caught up on the cover panel as it attempted to close. Also, I had a recurring problem where the cover panel would snap shut with well-tensioned force, only to activate the eject button on the CD drive, causing the disk to eject again. Adjusting the position of the optical drive back a millimeter or so seemed to alleviate these quirks. Bottom line: you can make this eject mechanism work with most drives, but you must pay careful attention to how everything fits together as you assemble the system.

Of course, no matter what you do, the drive cover will block access to any front-panel lights or controls on the optical drive beyond the eject button. Also, I tend to avoid pushing on drive trays in order to get them to slide closed. Using the button seems more civilized and less likely to cause problems. Alas, with the SB75S, you'll have to push on the drive tray in order to make it close.
