I disagree about the size but not about the weight, which is mostly dependent on personal fitness. I measured the extra volume my cramped midtower case made by nexus takes to insulate better for noise. Convection heatsink of that size can emit 25W per degree of difference between ambient and the heatsink. Assuming ambient around 20C, you can emit atleast 750W with reasonable temperatures for the components. This assumes fanless system design, not trying to put fanless individual components inside the case, but use heatpipes to transfer the heat to the case side panel which operates as heatsink.
Compulab airtop3 has high enough total power in a very small form factor that scaling its gpu 160w heatsink to 250w and upgrading CPU heatsink to that wouldn't make it particularly large design. Here's its comparison to other small form factor PC:s.

They would also need to increase PSU size for that also.
