This is my most recent built:
It consists of:
a. Ryzen 9 3900X CPU (comes default with the colourful LED-lighted fan)
b. Asus X570 motherboard: ROG Crosshair VIII HERO (WIFI)
c. Phanteks casing (which I regretted very much – it is so poorly designed. Once the ATX power goes inside, with all the wires jutting out from the powerbox, it eat into the space meant for the 3.5″ harddisk. So I can only have ONE 3.5″ HDD, which have spaces meant for TWO. And there are so many illogical wiring designs internally – endless defective design).
d. Corsair RM650 650W power.
e. GPU is from AMD RX Radeon 5600 XT
f. DDR4 Corsair Vengeance LPX 16GB x 4 (motherboard maxout at 4 slot for memory)
If you need comparisons there are tons of comparison out there:
