Best Pc requirements for this emulator

OK thanks, so it is better a desktop. If so, i can buy for example:

CPU: i7 9700KF or AMD Ryzen 3700X
GPU: GTX 1660Ti (or RTX 2060)
RAM: 16 GB DDR5 2666Mhz

I want this case: https://www.silverstonetek.com/raven/pro...a=it&top=S
So, i have to verify if I need to overclock the cpu. If so, I have to verify if i can install in this case an additional cooler..
