Thanks, as always, for such a wonderful job in explanation and photos as to how this disassembly and upgrade of the M4 Mac Mini. I and many others thank you for this work that you do so well. I have just purchased an M4 Mini with only 256 GB internal drive, although, I did opt for an upgrade of the RAM to 32 GB; but, as everyone knows, and extra $500 as a charge from Apple for this much extra RAM makes for quite an expensive addition to the cost. But, now that I have an option to upgrade the internal drive to 2 TB, my Mini will be really powerful, with lots of room to spare!
