Well, I've got a black Antec 1030 with beige drives. I didn't think it looked bad, but my girlfriend saw it and here's how the conversation went:
GF: Ooh, black case. So are you going to paint those black to match? (pointing at the beige drives.)
Me: Um, idunno. Do you think they look silly?
GF: Yeah, kinda.
Me: Um, yeah, lots of people paint them. I was just trying to decide if I want to go with black or some other color.
GF: It looks nice with the door closed.
Yeah, you know it, computer style is all about impressing the chicks. 'Cause you know, relationships hinge on these things.
(That was a couple weeks ago. I still haven't painted them. She hasn't left me yet, either.)
