AFIK, only the Bezel colour changes in Liteon drives while tray remains beige. With certain models you get Beige, Black and Silver bezels as options. Of course I maybe wrong.
Regarding the Black Tray = better writing quality story, only Plextor seem to have this theory.
Stone walls do not a prison make,
Nor iron bars a cage;
Minds innocent and quiet take
That for an hermitage;
If I have freedom in my love,
And in my soul am free,
Angels alone that soar above
Enjoy such liberty. - Richard Lovelace
