I dremmeled a hole in the back of the iMac, stuck the HDMI over it, then bolted it on with nuts and bolts. You can find similar ones for DVI and VGA. It is a couple inches long, female on both ends, and one end has extra screw posts where you can screw it to the back of a Decora plate. I bought an HDMI adapter that is normally used for running HDMI through conduit and installing in-wall jacks. My VGA control board for my 24' iMac used VGA+DVI+HDMI. You can't see them unless you tilt the iMac up, it's nice.Ħ) the Video-In. If you are concerned about heat, you can either: (a) splice into that soldered joint (pre-psu) and add a 120V-to-USB adapter and a 5V fan or two, or (b) splice into the post-psu 12v side and add a 12v computer fan.ĥ) the VGA Control Board's Menu Button Board: fastened this to the bottom of the iMac case (using bolts, nuts, and metal plumber's tape) pointing downward out of the uncovered RAM bay.

I placed the PSU inside the iMac case, and soldered the power plug to the inside of the iMacs power port, so that I can use the original white power cable to power the iMac. So find any old wall-wart or power supply you have lying around, just make sure your 12v psu has sufficient amperage. Most VGA control boards take the standard 12V that eeeevvvveeerrrryyything uses (usually 5.5x2.1 plugs). You can also use plumber's tape+bolts, or just hot glue and duct tape.Ĥ) The power supply. Based on the model number you provided, this would be your best bet:ģ) recycle screws and screw posts from the old guts to secure the VGA control board. Remove all components from the shellĢ) Install a VGA Control Board. I did this sucessfully with both an old 17' Powerbook screen, and an old 2007 24' iMac.ġ) Gut the iMac completely. YES you can convert your old iMac (or laptop or anything!) to a standalone monitor.
