Ouch... First time PC builders will love that. And everyone else who forgot printed manual at home, have feature phone, a phone without internet connectivity, phone with tiny screen, assemble computer in location with bad/non-existing internet connectivity, doesn't have a laptop on spot or have a laptop wit WiFi issues or phone without hotspot support or with limited data plan etc. This will screw up people in so many ways that MSI can prepare a noose and soap and be ready to burn in Hell for eternity. I totally agree that in name of resource conservation there is no need to have 80+ page paper manual in a box with each motherboard. However the box still must contain a page or two with motherboard pinout diagram, short description for basic things like which ports are default for 2/4 RAM module combinations, which used PCI-E ports will block which NVMe or SATA ports and maybe - short board technical specification.
Exactly. Also device drivers for major OS-es should be available in downloadable form at manufacturer web page without any need to obtain them via fancy malware soaked download managers.
