Unfortunately another one bites the dust. Check the underside of your boards as well guys!
Charged only with the FW adapter and once briefly with an Apple 61W USB-C PD adapter (pictured) which wouldn’t charge the system for some reason.
No external GPU but I was stress testing the system.
The one on the underside of the board was cooking my RAM a fair bit, it burnt my finger touching a module when I was trying to figure out the heat source.
