I noticed a cool looking black case that has a cover. Useful to hide those white Cd drives, huh? ;-). click here
or what about this Q-TEC TL-MD BLACK TRANSPARENT case: click here
It has siverish faceplates but your white CD-drives would look to out of place there.
A far fetched idea could be to stealth your Cd-Drives. This means attaching one of the faceplates to the front of your Cd- Drive, so you wouldn't even see them. Just an idea, lol.
