The integrated Intel graphics can power up to three displays, but the Radeon Graphics engine supports up to six 4K displays simultaneously. Unfortunately, the discrete Vega graphics will stay powered constantly during that somewhat extreme use case. The processors also support Radeon FreeSync Technology. Intel's HD Graphics 630 doesn't support FreeSync, so it's likely that using the feature would also prevent shutting down the Vega graphics engine, making it a power-sapping feature.
This does not sound like an issue at all. If someone has their laptop connected to multiple displays, they will almost certainly be running on AC power as well, so the slightly higher power draw wouldn't be a concern. The same goes for FreeSync. If you're playing a game with FreeSync active, you will almost certainly be running it on the Vega Graphics chip anyway, so of course it's going to be powered. When the Intel integrated graphics is being utilized for light desktop tasks, there will be no need for FreeSync to be active.

I know these are meant for the mobile market, but I would love to see something similar for the desktop. Video cards can be a real PITA to install and some are way too loud.
The problem with an all-in-one solution like this is that it would greatly limit your options for performing upgrades on a system. The way it is implemented here, neither the CPU or GPU are upgradable, as they are permanently attached to the motherboard, which is typical for laptops. Even if they utilized a socketed design for a desktop system, it would still mean that you would need to replace both the CPU and GPU together at the same time. Typically, graphics cards get upgraded more often than CPUs, since CPU performance usually doesn't improve all that much from one year to the next, but if they are on the same package, you would need to replace them both together, which would likely be more expensive.
Additionally, CPU upgrades tend to not be as easy as graphics card upgrades, so you wouldn't really be gaining anything there in terms of ease of installation. That wouldn't likely improve noise levels either, and in a desktop you would just needlessly be moving two heat sources together, creating one hotter heat source that might be harder to cool. That could be okay for these relatively low wattage parts, but more powerful hardware might best be left separated. Now if what you were looking for were a largely non-upgradable computing device with this kind of equipment, I'm sure those will exist. There are already all-in-one PCs built into monitors, and mini PCs in small packages that contain hardware similar to laptops. Or, of course, you could just get a laptop.
