Assembling a gaming pc

Hi hi! I got all the pieces for my dream gaming pc, the unfortunate part is I live in a rural area with no tech centers near me. I've never built a pc before or anything really like this, i'm nervous about a lot lol.

Is there any advice anyone could give?

I searched the subreddit but i usually find the topic being related to what parts are good & what isn't. I just need help / tutorial / advice on putting it all together. Would just youtube videos be enough to do it myself as a first timer?

Thank you so much for any help!
