Yea all those parts are, great but amazon and best buy no. I rather choose https://www.newegg.com/. and maybe like Ironside computers or Digital Storm
The i5-7600k, is rather preferred for me because it can get over 100 or 200 fps in CS-GO in high settings.
Logitech G230 Stereo Gaming Headset is rather preferred to because its more cheaper.
Asus VE228H 21.5" Full HD HDMI LED BackLight LCD Monitor w/Speakers is more cheap and maybe the same thing.
And that's it.
Its less than the PC you made on the top.
