You could definitely go eGPU + intel NUC and tape them together for 2x Switch + Dock. M2 nvme drives are tiny and I think some boards take laptop memory. You really only need the equivalent of a gtx 970 to do 1080p which probably exists in Pci x4.

Nuc makes a model called a Hades Canyon that is an awesome gaming rig for its form factir. 4k at mid-range settings, 1080p at anything you can throw at it. (And I'll be honest... Maybe I'm getting old, but from 2 feet away I can't tell the differece between 1080 and 4k.)

And double the "just spend $500 one time" initially suggested as being the solution.
