Not much of a purchase
16 February 2021 
relatively immediately buy 16x2GB or 32x2GB so that it will last for a long time.
Stylish, productive, +USB-C, many M2 SSD slots, PCIe 4.0, many coolers can be connected, +wireless Wi-Fi (but why do I need it if I have RJ-45?)
2 slots for RAM
Ae-Phase: use MSI MEG B550 UNIFY-X less than month
