If you have any trouble finding NUC or some RAM and SSD's at one eighth the price that Apple charges for the same thing just message me.
Maybe someone is going to offer to me next a source for Tandy, or Amiga, or Toshiba parts?
Yes, I knew when I wrote what I did about the NUC that someone was going to bring up ASUS.
ASUS was already selling small box PCs before they picked up the NUC remnants from Intel.
ASUS buying said NUC property/rights does not at all address my point: Intel discovered that the idea of the NUC was not an attractive business.
The day of the DIMM is over, and the same is slowly occurring for all the other bit and pieces with which you want to play. The reason you think those parts are cheap is because you are picking them up years after they were originally researched and developed. Retail system integrators of course want to preserve their business, like IBM of old, by continually convincing customers that a lifelong processes of flipping boxes, boxes assembled by integrators, is necessary for life.
But the reason the personal computer business is slowly fading is because people would rather have a smartphone (or maybe a tablet), and a smaller fraction of the world
might want a laptop computer for work.
And that laptop is becoming a closed box like that smartphone.
Contemporary manufacturing processes for the end-device are nearly completely automated, and the cost-effective way for the manufacturers is to make a single package.
And this is why, for example, Lenovo now offers computers with soldered in SDRAM (just like Apple), and while on some models Lenovo does offer one DIMM-type slot, Lenovo
charges more for that.
