I've been toying around with the idea of building a new PC after a long time of using a gaming laptop. I don't need anything cutting-edge, just some gaming and movie watching and what not. Looking for any advice, noticeable bottlenecks, or glaring red flags would be great.
For a $1300 build you should be on AM5 playing at 1440p with no issues.

Motherboard: Pretty much one of the cheapest options with wifi.
Cheaper and still very good storage more than enough of your needs.
GPU general rule of thumb is to go for the cheapest AIB (version), its black/silver so if you want can get pure black for 10 dollars more.
Case in general is personal preference but you choose a way too expensive one for no reason, this one is a smol like the matx you chose and really nice in my opinion
PSU is pretty much one of the cheapest high ends, you can save 20 dollars or so by getting a C or B rated.
