The NUC was a 2015 one, as provided by my "customer". So, it was not particularly fast! I at least changed the hard drive by a SSD to improve the speed. The advantage of this little NUC is to be able to use the original power unit of the iMac G4 to power and the display, and the NUC.
 
I finally took time to integrate the M2 Mac Mini, and it is ready !

Everything is ok, it has 3 usb 3 ports, 1 thunderbolt 3, one Ethernet, WiFi and Bluetooth are working very well, thanks to the new antennas, and the audio part is great.

It is able to use Netflix or any other vod service, the display is HDCP compliant, thanks to an integrated HDMI splitter.

I have one free thunderbolt inside, I’ll think about a way to use it.

The only limitation is the fact that the sleep mode does not correctly work. The display’s backlight does not turn off.
 
A great job. The Sonoma screen looks awesome on the iMac G4.

You must have had a lot of effort in getting this to work. I have a question. Would it be possible for us less experienced hobby workers, but probably more expensive, to use the Juicy Crumb Docklite G4 technology from Australia (https://juicycrumb.com/product/docklite-g4/) to provide the interface base for M2 Mini in the G4, as shown by Action Retro in his video

thanks for the link, I did not know this great solution! I think it is perfect for those who don’t want or can’t do the modification themselves.
There is still the issue of the Mac Mini integration if you want to have an all one one, and not just as external display.
In my opinion, I have to add that I hate the look of this solution ;-)

Unfortunately, that solution is only for the 20" iMacs... for now.

EDIT 12/5/2024- Not anymore. 17" 1.25ghz models now have this board available.

Your work is so impressive and i agree is much more elegant than using the Juicy Crumb board specifically for an M2 upgrade rather than just using the G4 as an external display.

Would you be interested in providing an M2 conversion kit for others to fit themselves? Would this even be possible for those of us who don’t have your soldering skills?

I just got hold of a 20” that I really want to do an M2 upgrade with, but I want to retain the original ports, power button etc and your modified logic board is the best solution I’ve seen!
 
I finally decided to upgrade a 17” with a new display!
This is a full HD iMac “G4” !

The LCD comes from a 17" unibody MacBook Pro, and I installed the control panel on the dvd drive door. Efficient and elegant.

Did you reuse the TMDS wiring in the neck or crack it open to run the LVDS lines for the MacBook Pro LCD through to the controller?
I’ve been considering putting a 3840x2400 17” panel in a 17” G4, but I haven’t found a good source for a long enough eDP cable to run through the neck yet…
 
I opened the neck and integrated a LVDS extender and some other wires to power the inverter and to cable the mic.
I put the inverter behind the LCD panel, and the controller in the base.

And let me introduce you my new 20" iMac G4 M4 !

The Mac mini takes place upside down, and the two usb c of the front are accessible through the drive door.

The original power supply of the iMac was dead, so I replaced it and hid a button instead of the audio jack in. Almost stealthy !

The other side is as usual on my mods : 3 USB 3 and a thunderbolt port.

This is a cool mod, very clean. Although not a Retina display. One of these with a Retina display would be a very usable and interesting experience.

Sadly, we can’t find any display with the ratio of the original one and a good resolution…
