Intel LGA1851 / Z890 - MSI vs. ASUS Features and X870E Boards

MSI is showing off Z890 & X870E motherboards at Computex 2024 -- and Intel is a control freak, trying to prevent anyone from knowing that its next socket is "LGA18XX" (it's 1851) - but even 18XX has been known for literal years now, and yet Intel thinks it can put that genie back in the bottle. Bizarre Intel control behaviors aside, MSI has new motherboards competing with ASUS on ease-of-installation features, a new case with some unique fans, and an AIO with offset mounting for Intel's upcoming Arrow Lake CPUs.
