Getting a pc for christmas but worried about stuff

[alfiee]

Im getting a pc for christmas but since it costs so much money im very worried about everything. Are the case & motherboard alright? And will i actually get what i order and will it work (ordering from amazon). Those are my concerns
800 euro budget (900$)
I want a diff motherboard since its a mini one but i dont have alot of knowledge about motherboards.
the build:
GPU - GTX 1060 6GB
CPU - Ryzen 5 2600
MOTHERBOARD - MB ASrock B450M pro4
PSU - seasonic 550w gold
CASE - Aerocool Aero 800
MEMORY - 16gb xpg gammix d10 3000Mhz
STORAGE - kingston 480gb SSD

Also, since i am trying to save as much money as possible can should i go with 2400 mhz instead of 3000?

I see no issues with any of the listed parts. Personally, ASRock is my first go-to brand for motherboards. I've had very good luck with them. ASRock does have standard ATX, Micro ATX and Mini-ITX versions of that board available.

I have no personal experience with that case, but it looks fine to me.
