A normal desktop with non-soldered components is more repairable, cheaper and can also run on stock Linux?

The only selling point is the form factor and a massive amount of GPU memory, but a dGPU offers more raw compute.

OSS is fair.

From the product page I don't see how that mainboard is more repairable than a typical ITX one though. As far as I can tell, you also cannot change the CPU on it so even less than a typical desktop mainboard.
