@GabenJr I am currently in the process of training to be a certified AppleCare Technician. If I’m not mistaken, getting this certification would allow me to access Apple’s Global Service Exchange, or GSX, which is their internal portal for component purchases at wholesale. I’d be more than happy to help, considering LTT has inspired me to love technology even more, and a main influence for me to start pursuing the AppleCare Technician certification.
By the way, a lot of posts on this forum say that there’s no repair manual yet for the iMac Pro. I’m pretty sure that’s not true. I’m pretty sure I remember looking through it.
