The very ambitious, fully aluminum, high end Aurora case, the first from Gigabyte of its type:

" The nifty part of the front is that the LED from the fan can illuminate a logo onto the ground (or desk). The principle behind it is simple - light cannot penetrate black, so by using a stencil, which can be found here, you are able to project any word or image onto the ground. Nifty trick, and is probably why the bottom half of the case sticks out a bit."
