first build help pls

Hi this is my first pc build and i don’t have anyone to ask so hi reddit! I just wanted to make sure this build would be compatible, especially with my lian li a3 case which i have the microATX for but im not sure if the other components will properly fit inside. any tips or advice is appreciated thanks :)

my budget is preferably around $1400 usd
