functionality..... what good is it if it looks slick, but doesnt work? aesthetics..... what good is it if it works, but looks crap? but then, i'd be happy with a beigebox that works, rather than a super-flashy bl00 box that doesnt. uniqueness..... to a point. i like my things to be unique in my house. i dont really care if someone has made it before somewhere else, i like each thing to be unique to its purpose.
Aesthetics and form vs. function. I don't think the case should do more than hold the PC together. I believe in clean, smooth lines, and a shiny paint job. Something that isn't outrageous but not subtle either
