While waiting for an iFixit teardown or OWC memory installation video, I came across this Macworld unboxing that opens up the case near the end. Skip to 7:55. From Tom's Guide: "So, even if you have a set of tiny Torx drivers, you'll probably need to get a different screwdriver, one with a hole in the center to accommodate that pin. Specifically, you'll need a driver for a TR6 Torx security screw." https://www.tomsguide.com/us/mac-mini,review-5908.html Along with an opening tool like for the 2014 Mac Mini (or a credit card): https://www.ifixit.com/Teardown/Mac+mini+Late+2014+Teardown/30410 After that, there is a cable attached to the wireless module/antenna, removal of the fan, and the memory is in a cage. Until we see an official teardown or guide, we don't know what other tools are needed to do a RAM upgrade. So based on this, are you still thinking of installing your own RAM in a new Mac mini? For a 16 GB upgrade, I think the Apple pricing is within reason -- when I consider buying the RAM and tools separately, and the time to install and test the memory. Beyond that, I feel like Apple's pricing is out of line and difficult to justify.
