Pardon the hyperbole, but boy, this is something else.
Designer Hiroto Ikeuchi calls his PC the "secret base".
Most PC casemods are content with using some paint, maybe some basic custom cases. Ikeuchi's is more like a work of art.
Wired says his PC is inspired by stuff like Gundam and Macross. No matter where you look, whether it's, monitor, keyboard or tower, there's something going on, some little hidden treasure.
Not all of the embellishments are just for show, either. That tank is the PC's mouse, and there are eight pieces of heavy artillery that are actually USB sticks!
There are more of these wonderful photos on raku-taro's tumblr (which is itself an awesome way to spend a morning).
