Just chiming in that I thought the same thing, but, I doubt it matters much. I have a laptop that hits 95C by design and manages to keep the WASD keys cool while doing it - it is more about if they have a proper setup for cooling the GPU and CPU, and if the monitor produces a lot of heat or not (doubtful). The ambient temperature inside of the case may go up slightly, but that heat is going to be miniscule compared to what is coming off the CPU and GPU at any given time and *hopefully* being diverted away in all three instances.

I'm inspired to do this set up of yours because I have a limited desk space. PC below the desk always gets dusty from my dogs fur. Its always a hassle for me to clean my pc every month
