can i take out the pre built fan on a retail case and replace it with a new one?

Solution
Sure you can take them out and replace if you want.

I would try it as designed first, and see what happens. If too loud or too hot, then see about replacing some.

Noctua fans are very quiet and last a long time. The stock fans will probably start making noise about 2 years after running whereas noctua fans won't. That's the only difference really. I would recommend using the stock fans until they start making noise.

I'm going to get a CPU cooler for the CPU, and since there are stock fans already in the case itself, i don't plan on attaching more fans. if it's too loud i'll replace it with the noctua fans.

is this a good build for the case? or do i have to attach some extra fans within along with the stock fans?
