I've always wanted a Pyramid PC.
Now, there are two ways to go about this. One could be Jon Ive-y and make something subtle and sleek, a little brushed metal thing on your desk that gently glows at the peak when sleeping.
Or you could roar "Pyramid Power!" and make something like polo360x's amazing and enormous machine, which makes Las Vegas's Luxor hotel look like a Lamplighter. [Tech Power Up] (Thanks, The Dulcet Tones of Terry Wogan!)
