On X, L0vertodream also posted on X a Mac mini teardown. L0vetodream states that “it is indeed a 1-slot dual-slot with a maximum particle size of 1TB. It uses a BGA315 hard disk and the maximum upgrade capacity can be up to 2T” [translated]. Read our in-depth review of the M3 Pro Mac mini.

Another interesting move on the cooling front is that the Mac mini with vanilla M4 has an aluminum heatsink, whereas the model with the M4 Pro SoC has a larger copper heatsink to better cool the more powerful processor, which makes sense of course.

Apple isn't soldering the SSD to the logic board in the M4 Mac mini, but given the company's history with Apple Silicon, don't expect upgrades.
