Raspberry Rackmount

What was the intention
==================

I wanted to place several Raspberrys into a 19" rack and operate them as server-cluster. A requirement was to change the SD-card from the front and to make all USB and network connectors available from the front.
I found a lot of different raspi cases, but none fitted my needs.

What I did
========

I bought a 19" ABS rack case and printed the raspi-holders which replace from now on the frontplate. To fully close the case there are also spacers needed to fill the gap between the raspis. You can customize them and use them for power switches or a reset button per raspi.

Which parts used I
===============
The 19" rack case and the SD card holder I got from the German dealer reichelt.de
