Case designed for a Raspberry Pi2 + HiFiBerry Digi shield. I use mine as a dedicated Musicbox -> http://www.pimusicbox.com/ You can also use the HDMI from the Pi, but I could not get a stable connection on my Denon amp. The top of this case is compatible with the bottom of this one: https://www.youmagine.com/designs/raspberry-pi-2-case-with-mounting-bracket Which is based on this one: http://www.thingiverse.com/thing:922740 In case you want to modify this design, you'll find the .stp file here; https://www.youmagine.com/designs/hifiberry-digi-raspberry-pi2-case 4x M3 x 16mm to mount the Pi+HiFiBerry print the 4 spacers to go between the Pi and the HifiBerry 4x M3 x 40mm + locknuts to close the case (assuming you use the wallframe/foot)
