I think these have pretty high prices (as I acknowledged in my first message), but they exist. And I see similar things all over the place in retail and medical settings.
Here's a recent AMD processor one from Lenovo https://www.lenovo.com/us/en/p/desktops/thinkcentre/m-series...
Here'a a Dell with Intel. I can't decipher Intel's model numbers, but it's DDR5 so it can't be that old. https://www.dell.com/en-us/shop/cty/pdp/spd/dell-pro-qcm1250...
1 litre micro PCs are about 4X (35W+) TDP and price of Intel N150 with 6W TDP. They do offer more performance and features (e.g. security) than N150, but exist in a separate and stable (15+ year) category of business desktop.
Mini-PCs have a range of experimental form factors, including mini-desktop, NAS, router, tablet, SBCs, industrial with GPIO, thanks to competition between Chinese and Korean (e.g. ODROID) OEMs.
HP has a $220 4GB Windows laptop and $400+ 8GB Chromebook based on Intel N150.
