It really depends on the theme you want to show on your case and what color lights you want to put it... however, I do like gray/black (Any color lights go with that combo because they are neutral colors).

Theres too many colours you could do to list them. Black red? red white for instance. Really depends on theme though, i have to agree. Best ones are people who air-brush them and paint patterns.

dark green / silver

I like when the X is painted yellow and the vents are left black.

just a question, why is there white and blue, then blue and white, lol.

i think that red and black look pretty good.

blue sliver

I cannot recall who it was, but they had two boxes. One was the fire box and one was the icebox I believe. Those two were exceptional. It is just amazing what schemes can be done outside of the normal two-tone.

purple and green is fucking hot.

Dark Gray for the X, and Gray for the rest.

Blue and White! lol
