Hulk smash Hardware! Hulk angry!
For starters it's pretty awesome that this mod doesn't even really consist of a PC case, although the hard drive and DVD drive are contained in the base. Some might say this would collect a lot of dust but hey, a PC case does anyways, and this is a lot easier to dust off! Plus it's open-air so should run cooler.
They de-manufactured a couple of Hulk action figures and motorized the arms so he could wave the motherboard around - genius! HULK CRASH! Instead of having the power supply be some sort of separate afterthought-looking thing (like many of my creations, unfortunately) it's right out there in the action, with the Hulk standing on it.
