Java Cluster: Hardware

I'll first show the Hardware setup then later show the Software configs.

The hardware is:
4 x Raspberry Pi Model B rev 2 (512mb)
4 x Raspberry Pi Heatsink (keeping it cool!)
2 x Stackable case (https://www.modmypi.com/blog/multi-pi-assembly-guide)
4 x Short Networkscables
4 x short Usb-Micro Usb
1 x Deltaco 7 port Powered Usb-hub (http://www.dustinhome.se/product/5010144399/deltaco-usb-hub-7-portar-usb-2-0-svart/)
1 x 5 port switch
4 x SD-cards (8gb or higher class 10)


First set the Heatsinks (cooling paste is already applied)

I choose to angle them sideways if I want to add a fan at the side.

Next is to screw the Raspberries to the cases and stacking them. 

Connect the Network cables to the switch, the usb cables to the usb hub. 
Connect a cable from your modem/router to port 1 of your switch (should give all your raspberries access to Internet).



All that's left is fixing the SD-cards. But that is a part of the Software explanation.
(Turn on the power AFTER all the SD-cards are fixed)
