I setup a Raspberry Pi 3 to experiment with ROS, OpenCV, and whatever else I felt like looking into, and I wanted a desktop case for it. I started trying to duplicate the look of the Intel NUC stuff, but ended up doing a "micro" version of a desktop PC tower case.

The basic specs for the setup are:

1. Raspberry Pi 3 with WD Pi drive (314GB) as the boot disk. (No SD card at all)
2. Pi camera
3. Adafruit audio amp driving stereo speakers (Okay, they are a bit close together.)
4. Pi and HD LED's moved to the front panel.
5. Adafruit 128x64 OLED display and four buttons. Used for menu system to start stuff, show status, and reboot/shutdown system.
6. All Pi USB & Ethernet ports brought out to panel mount sockets.
7. Pi serial console port connected to USB serial adapter on back panel.
8. Variable speed cooling fan, speed based on CPU temp.
9. Raspberry Pi logo on case side.
10. Clear removable window on other case side.
