This is my DIY project of Volumio.
I have changed the stylesheet so the green colors are now blue and shows my logo in the top-left corner.
The front has a shutdown button to protect the SD card. A python script runs in the background waiting for a button pressed on the GPIO port and then does a ‘shutdown -h now’
The output ports on the back also includes HDMI for if I want to use a TV to check the config when (read: why) no network is active. It can also be used for when I boot with XBMC.
The output is analogue, using the HifiBerry DAC. Inside the case is also a USB hard drive with FLAC files. This SMB-shared directory can be accessed by a Windows computer to put music files on it. On the USB port I have put a Wifi dongle so there is no need for wired network. (and the sound-quality from the DAC seems better with WiFi). The player also supports Airplay and acts as a Squeezebox client.
EDIT: I have also added a schedular to plan the playlists to be played:
