made a small cross frame so those black bezels are now hidden.
I used an es9028 pro dac and used the i2s input of the dac where the usb board is normally located.
Furthermore, a 4.3 inch touch screen, rotary encoder, infrared receiver, status LED of the raspberry pi, separate on/off switch for rasp and es9028 board and a screen for the dac.
only thing I want to change are the 4 big black nuts on the front I think they are a bit too flashy.
and also spray the top plate black again.
