Inspiron 5680 motherboard vs XPS 8930

both microATX

both Z370 chipset

8930 has bios update to support 9th gen cpu

5680 bios can support 9th gen cpu too.

other than bios and different layout of the mobo, is there any advantage of 8930 over 5680, or the other way around.

I have a chance to get a 5680 for small cost.  but I really do not like the 5680 case.  so plan to move 5680 mobo into a third party case.  any one done this and is there any Dell proprietary USB trick I need to know to avoid startup error (such known in 8930 case swap).
