Looking for Help with My First PC Build for Gaming

I'm diving into PC gaming but I'm totally new to building a PC. I've got some recommendations for components but I could really use some advice on whether they're good choices. I'm interested in games like Fortnite, Call of Duty, and Rocket League, so I want to make sure my setup can handle a variety of games. Here's what I'm considering:

**CPU:** Ryzen 7 7700
**GPU:** RTX 4070
**Motherboard:** MSI B650 Gaming Plus WiFi or MSI B650 Tomahawk WiFi
**RAM:** 32GB DDR5 6000MHz (2x16GB) - Corsair Vengeance, G.Skill, or Teamgroup
**Storage:** 2TB NVMe SSD - Samsung 990 Evo, WD Black SN850X, or Crucial P5 Plus
**Power Supply:** 750W Gold PSU - Corsair RM750e, MSI MAG A750GL, or Seasonic Focus 750
**Case:** NZXT H5 Flow, Lian Li Lancool 216, or Corsair 4000D Airflow
**CPU Cooler:** Thermalright Peerless Assassin.
I'm feeling a bit overwhelmed, so any insights would be appreciated!
