Help checking specs before cybermonday ends!

Hello everybody! I've recently wanted to build my first pc, and wanted to know if these specs are alright or not? I'm pretty new to the newer tech (gen 5 ssd, 50 series, AM5) and tried doing my research but wanted to confirm with people who know a little more than I do.

Specs:
CPU: Ryzen 7 7800x3d
GPU: Asus TUF RTX 5070
MOBO: MSI MAG B850 Tomahawk MAX WIFI
PSU: MSI MPG A850GS PCIE5
RAM: any DDR5 i can find tbh
SSD: Samsung 9100 Pro 2Tb
CASE: Asus A31 ATX (I like the slant)
CPU COOLER: ARCTIC Liquid Freezer III Pro A-RGB
FANS: 9x DARKROCK F120 120mm (3 on AIO, 3 on side, 3 on bottom)

I was also hoping for a little insight on whether or not to get the X870 motherboard, it's $40 more on amazon but I have prime and the B850 doesn't have a prime seller. For ram i was looking at G.SKILL Trident Z5 Neo but idk. Any help is appreciated!
