This type of design isn't useful. Round things don't fit neatly anywhere on a desk. Air cooling makes no sense when your design goal is high performance in a small space. What would really be useful is something 2.5" thick and as long and wide as necessary. Think about it you could lay it flat on your desk and put your screen on top of it, stand it up behind your screen, hang it on the wall behind your screen, bolt it to the under side of your desk, bolt it to the back of your desk, or bolt it to the side of your desk.
