Designs, schmesigns, a mobo isn't a piece of art. You want art go to the gallery. Mobos are basically and ultimately tools. Their function determines their form. The medium is the message (Marshall McLuhan). It is only serendipty that they have any aesthetic.
But, alas, beauty is in the eye of the beholder.
Give me an ugly bitch that can OC to 6.0 GHz and be damned with your ideas of beauty.
