I imagine a white PC fan would look terrible if not cleaned daily or used in a room with very filtered air.

Totally. I used to favor black a long time ago when most computers were still gray and the idea of having everything in black was really cool, but since realizing that details and controls are harder to discern on black, I’m all in on white and silver. It’s also less prone to showing fingerprints.

Have we solved the yellowing? I guess many of us have memories of old and ugly yellow computers.
