About $100 cheaper compared to elsewhere. It is bit expensive for what it is, but these premium ITX Z690 motherboards haven't really come down in the price over the past year.
Scorptec $639 - https://www.centrecom.com.au/msi-meg-z690i-unify-d5-wi-fi-lg…
PCCG - $599 - https://www.pccasegear.com/products/56422/msi-meg-z690i-unif…
CentreCom - $589 - https://www.centrecom.com.au/msi-meg-z690i-unify-d5-wi-fi-lg…
Edit: BPC will do BIOS update for $10 to support 13th Gen.
I'd love a mini ITX but soo much more expensive than mini ATX for MB, case and power supply.
