I want to believe there’s a laptop RTX 4090 in this surfboard of a custom handheld.

Look at this thing. According to Videocardz and Tom’s Hardware, it’s a custom 12.5-inch 4K handheld with Intel i9-14900HX and Nvidia RTX 4090 chips from a gaming laptop. There are pics and a video of it playing games, but none showing the build or internals.
