I have a GDEMU, PICO-PSU and Noctuna/W Mount. It seems easy to add power for the Pi Zero W with the PicoPSU. I also replaced the thermal pads on my DC. With the new psu i think the noctua is pointless, I think removing the stock PSU & GD is enough and no fan is needed, if I wanted outdoors summertime gameplay or in the work truck (I DO) this mod looks like a better solution after the mods ive already done

About the DCHDMI, wayyy too pricey, a nice POUNDHDMI OR VGA to PORTTA to HDMI or VGA on a 4:3 or a 5:4 LCD is a better option. NOT WORTH THE MONEY
