Can't do part two so part one for market research is case number 2.
Firstly, it's not black as I'm so fed up with black computer parts. As black was probably great after the Bakelite era. But now it just generic, cheap to use and tacky in most cases. And it shows up finger marks and dust too easily.
Gone for the silver front as it compliments the light characteristic of the white body, and is more compatible with colour schemes in the home and future re-decorations. And while I would enjoy a more vivid front cover like number 3, the more style conscious people would be dumbfounded by my choice.
