CPU: I've always wanted to use this processor. If you're just gaming, this is a not a bad starting CPU for $50.
MB: Sale, 4 RAM slots, M.2 SSD slot.
RAM: NEW. Came with a pre-built desktop
STORAGE: NEW. Came from a pre-built desktop
GPU: Sale. Performs better than 1050 Ti in PUBG (since PUBG is the one of the most popular game).
CASE: Good airflow. TG.
PSU: Sale. I admit that I did not do a lot of research on this. When I saw this on sale for $15, I grabbed it. Just did not have a chance to update the price.
Fan: Does the job.
