As a former Mac Mini owner, and a happy Intel NUC owner, I have one suggestion to Apple regarding the Mac Mini. Make it more like the Intel NUC. Apple should be completely embarrassed that Intel has made a better Mac Mini than the Mac Mini. If Intel can do it to perfection, Apple should be able to do it. But with the direction Apple is taking with its hardware design, an updated Mac Mini is going to be even more locked down than that abomination of a Mac Mini Apple released in 2014.

Apple is losing to Intel in the Mini-versus-NUC battle. Ten+ years ago the Mac Mini was a very interesting machine, small enough to stick in a corner so we could put our computing where we want. But Intel's NUC is a better Mini than the Mini ever was, and Intel is selling a ton of NUC's. Apple should be ashamed of themselves.

The 2014/2015 Mac Mini is still, in 2018, the "current" Mac Mini model, and its biggest problem is the great difficulty to upgrade the device. While it is impossible to replace the memory it is possible to replace the hard drive, so long as you bought the upgradeable Mac Mini. Namely the version sold with an HDD. The other, with PCIe SSD, does not support upgrading the disk. You can save some money by purchasing the HDD version and upgrading to SSD on your own, however performance is higher with the PCIe version. The videos attached to this post document the overly unnecessarily difficult process for upgrading such Mac Mini's to have an SSD. You have to remove everything just to swap the disk? And you can't change the memory? The Intel NUC is in the same class of machine, and does not require this kind of over-the-top surgery.
