The original idea was to position the RasPI like this: http://imgur.com/TegDpOQ but we have problems to get connectors that are high enough above the board. To operate the board we rotated the connector and connected RasPI in an awkward way (http://imgur.com/jV1iis9). We will fix this later but even if You decide to use cables it would be better to reserve more space in front of the M-board for the RasPI.

=> put the fans on the opposite side.
