Through a Slack channel commented to me about this project did not know and that I was surprised by their appearance. A user has pluged in no more and no less than 15 Raspberry Pi in this monstrous box with which you can invoke Arioch.
The premise, as their author said, is create a portable, self contained cluster of computers that only requires a single power cable and an Ethernet uplink cable to operate.
1x Cheap toolbox from Home Depot
15x Raspberry Pi 2 Computer boards (1GB RAM ea.)

Ubuntu 14.04 LTS image loaded on each
300W SilverStone SFX power supply
Netgear 16 port Gigabit switch
120mm Noctua Fan
Arduino Pro driving gratuitous power LEDs up top
With 15 Raspberry Pis and 4 cores for each one, I'm pretty sure you can perform these tasks with costs us hours. More details on the following link.
