I put this together for my sister in law for christmas. i’m using a 22" monitor in a wood box i made with my dad. i ordered the glass from a local store, the dimensions on the mirror is 14x24". I have to say i cant believe how nice this turned out, i almost want to keep it for myself, but i think i’ll probably just make a second version down the road.
I added a back to the mirror and drilled some holes for ventilation, but i may either take it off or drill a few more since i’m getting the temperature indicator on the screen.
