PCs tend to take the "as many buttons and lights as possible" approach.....oh and stick "Intel inside," "Nvidia inside" and "Vista inside" stickers all over the covers and insides. WHY???
That is why I like the appearance of my Antec 900. It has some manufacturer stickers I chose to put on it, and its got awesome blue fan lights that illuminate my room at night when I'm using it. It goes well with the blue glow of my Saitek Eclipse keyboard and the blue and black color of my Logitech G5.
Macs look very boring to me in comparison.
