Hello,

So I am currently planning a build that involves an iMac G3. I want to retrofit a modern hackintosh inside and want to mount an lcd panel to replace the screen that is installed. My plan is to use a 13inch 16:9 screen and add bezels on the side. The issue I am running into while planning it out is powering the screen. I found a few LCD panels that can fit as well as control boards with HDMI out. These control boards require a DC 12V connection to power the screen. I am aware the 6 pin connector on a power supply can supply 12V and was wondering how likely as well as difficult it would be to rig this up. I have no electrical background what so ever. I know it would be easier to run a 2nd power cable out of the back of the system to power the monitor but I would like to make the computer as minimum as possible with the exception of being able to connect a 2nd screen (because come on, 13 inches isn't enough). Is this plan far fetched or do I have the right idea on how to achieve this.

I wonder if the chips used in this build would help, could use it to power the screen with a usb c port?

I've seen this, however I want to avoid using ports on the motherboard. Since I will need to use a MINI ITX board, expansion is kind of limited. Worse case this is a good option though.

Im not sure how electrically safe idea is however. Maybe a sparky will see this and can input?

I didn't even think of molex! I try to block it out of memory honestly. That might be an idea.
