Looking for Something Special for the front of the case

I am hopefully going to be completing a new computer build from scratch soon.  I have the Antec 900 case, and it is pretty snazzy.  But...  I'm looking for a little something that can be thrown onto the front of the case, to make it extra special, on the outside.

Years ago, I had seen at a computer convention, a small LCD display that fit in one of the 5.25 slots, that had a digital readout, of the graphics equalizer.  When your music played, you got to see the beat and (sine wave?) as the music played and changed.  I thought it was awesome.  I'm looking for something cool like that, or even that.  I've seen a few where you can control the fans of the computer... not as interesting.

Anyhow... anything that would be something awesome that would wow customers, I will consider.  Thank you.
