Lego case for my Raspberry Pi v2.0

After building the first case for my Raspberry Pi with Lego pieces, and thanks to some advice from some of my friends, I decided that my first case needed some (if not many) improvements.

For the second version, I took my time and found pieces of the same color, in this case, red. I chose this color because I wanted to put some holes for ventilation and the only pieces I had where red. I also put small doors for the RCA video connector and the audio jack so that I can access them easily. I also put a couple of hinges on the cover so I can have easy access to the inside. And finally, my idea is to overclock the board and to do this I need to use heat-sinks on the chips, I placed a small fan to help with the circulation of air.

This is the result:

UPDATE: A short time ago, a reader made me notice that I mention heat sinks for my Raspberry Pi in this entry, but that I don't post any pictures. Well, with my most sincere apologies for this slip and the delay, here there is a couple of pictures of the board with the heat sinks:

Determining where the heat sinks should go was easy thanks to this great article (in Spanish, easy to understand just by watching the pictures).

Lego case for my Raspberry Pi


Versión del blog en Español aquí.

I won a Raspberry Pi at the competition. I needed a case and since the student's life is really poor, I used my old Lego pieces to make one. I apologize in advance for the poor quality of my pictures but the camera in my cellphone is really bad.
You can see in the picture above that the place where the Raspberry Pi stands has small pieces. This is so the circuits don't touch the bottom. When I was assembling the structure, I thought I was going to have to use a tool to modify some pieces for the board to fit inside, but it turned out the Lego pieces had the precise size and everything fits perfectly.
For the cover I used other pieces so they hold the Raspberry Pi still once everything is in place. The next couple of pictures show the case finished. 
The following picture shows the Ethernet and USB connections. 
HDMI connector.
And the SD memory card and the hole for the power supply pin.
The other connections are covered by the pieces, but if I ever need to use them, I just have to remove some of the pieces and open a hole. Really easy.

As it can be seen, all the pieces have a weird discoloration. This is because they're really old, but I couldn't be happier with the result.
