Well, the two chips I mentioned (DGX Spark uses the GB-10) are both a SoC, so no motherboard needed there. I don't know if that's the full explanation, but it could be a factor.
The SoC design with unified memory is generally well suited for residential use because it's quite energy-efficient, quiet and small (compared to traditional GPU-powered gaming rigs). Great performance-per-annoyance, so to say.
According to the article, because components are really expensive right now, particularly RAM and storage.

Mini PCs (NUC-ish form factor) are selling a lot now too, small, quiet, most people don't need expansion over what you can get from eg USB4.
