If you're intending to bake this down to a normal map for a low poly model you might want model your edges so they aren't so sharp. By exaggerating some roundness on the edges of the high poly model you will get more of a visible edge on the baked normal map which in turn will help sell any specular highlights along those edges.
If you are not planning to model the front panel and the border around it on your low poly model, then you should model them like _/¯\_ or ¯\_/¯ on your high poly not at 90° angles like _|¯|_ or ¯|_|¯ so that they show up better when baked onto a normal map for the low poly.
