I originally had all my parts black and only the motherboard had white accents. I recently moved to a new country and was getting new furniture, case and everything except the parts inside. I purchased a white table (because I couldn't find a good black one or a nicer wooden one in the size I was looking for) and a white chair to match the table. I then realized I should probably purchase a white case as it matches the room and my new setup. I then embraced it and purchased a white case and set the lighting to purple/white or cyan/white! All in all I think it looks kind of neat

My primary colours are White with most of the inside going light blue
