overall seems pretty good from what i know

i don't believe you NEED the liquid cpu cooler, but it doesn't hurt if you have the money for one.

500W psu should be sufficient

for the RAM, getting 2 sticks of 8 is better than 1 of 16, unless you plan to get another stick of 16 soon.

if you already have a hard drive, you might want to invest in a SSD, pretty sure they're really helpful when it comes to stuff like boot up time, and other stuff idk, but do research.

someone correct me on any of this if it's false info
