is there a way to make a pop-up cd rack that uses 12v and a motor?

I want to build a few pop-up parts for my pc station. One of them being a CD rack that stacks the CD's vertially and can, at a push of a button, raise itself up through the hole in my pc station, and back down again (see the pop-up kitchen spice rack). I know this is probably achievable given that there are many motors that will run on 12v, but i cannot work out how it would lift or how it would stop at the maximum height before it comes up against the edge of the desk etc.

use a dpdt rocker switch connected to the motor.

use this link to wire the motor.

I would then use a rack & pinon setup on the motor. the motor would get a gear, and a flat piece with gear spokes on it would be mounted on the popup piece.

Any mpre questione, just ask.

Thanks thats cool. I also found a web site that allows me to create a rack and pinion template so that i can print out and create on of my own. Coupled with a 12V motor from bay i should be on my way to a pop up cd/dvd rack at a push of a button. Watch for the instructable!
