If I ever finish the frame I could put it inside.
Could you build the power supply first? Then you'll have to build the frame. :-) I don't know for sure that the electrolytic capacitors have to be low ESR, because the picoPSU is switch mode. But I don't suppose there's enough capacitance on the board to let us get away with ordinary electrolytics?
