Hijacking my own comment since this blew up. I want to clarify a few things that keep popping up:

Yes, a laptop is better for this use case. M1/M2 MacBook, 4090 laptops would all be more convenient than this. I already had all these parts, needed them to be mildly portable, and I had a lot of fun building it.

The thermals are excellent, what isn't pictured is the ventilation on the bottom and side.

I am working on a solution for the viewing angle.

The build is essentially from 2018, but the monitor and case are newer. The frame is built of 2020 aluminum extrusion, and the panels are 3d printed. 

Not pictured here is the pelican case that it goes in for shipping or checked luggage.
