Thank you very much for your answer. I already have the HDD and enclosure. What would you recommend for a CPU?

in my opinion, this cpu is not really worth it anymore if you are putting together a gamer pc.
However, if you want to take advantage of the cybermonday percentages, the lineup looks good.

but you should order a hdd (today's offer seagata firecuda sshd with additional product "assassins creed origins).
and a case would also be advantageous
my recommendation: something from be quit or fractal define :)
