This is an example of a front panel made from PCB by ELECROW. It shows a non-standard use of PCB, where the board was used as the front panel for a DAC enclosure. As you can see, the black PCB looks very good, and one of its main advantages is that all labels and markings can be made in a very neat and professional way, which would be difficult to achieve by other methods. The overall manufacturing quality is good, and I can also recommend ELECROW for this kind of non-standard PCB application. The only downside is that thicker PCB options are quite expensive.
