This model got on my radar because of the 8:5 aspect ratio and large cursor keys. But I seem to recall that the EU price was €5000, not €6500 for an RTX 5000 configuration. It might have been slightly different, but I can't see anything that would explain a €1500 difference. If it really is 6500, then it's too much. 5000 would correspond to the components. I think a comparable P17 is around 5500. And I doubt Asus can compete in support.
It really comes down to the GPU. Quadro RTX 5000 is very expensive (more expensive than 2080 Ti was). And the people who need that kind of GPU, don't necessarily need the most powerful CPU. They went with Xeon, rather than a cheaper Core processor, and sacrificed some multi-core performance (for example, Lenovo charges more for a 6 core Xeon than an 8 core Core in the P17). It could probably do well as a CAD workstation. You can criticize the limited options, but I don't think this particular configuration deserves it. It's certainly niche. But pretty much all workstations are. Workstations are not like gaming computers. You can have very imbalanced workloads and you tend to stick with them. And because high-end components are even more expensive as the market is small, you don't want to pay for something you don't need.
