Phaaze88 Thank you. Some background: This build is potentially for a friend with a six year old, completely unstable build, that reboots multiple times daily. We both have a friend-in-common, that's offering to buy the build above for him. With that said, I don't want to financially compromise him, therefore I'd like to offer a lower-price option, just in case it's necessary. I was thinking about: Intel core i5-10400 ($155) / cheaper LGA 1200 MB / cheaper GPU (Maybe 1660 Super, if one could be found).

Follow-up questions: Is 10400 reasonable CPU for gaming and if so, what motherboard would be reasonable to compliment it with. I really like the B460M Mortal, because of the integrated wi-fi, but not sure if a $125 motherboard is foolish with a $155 CPU. Also, what's a good 1080p gaming GPU. The friend that'll receive this gift only has a 60 Hz display at the moment, so any computer that doesn't randomly reboot is an upgrade at this point. Thanks, and I understand if you don't have time to read my verbose follow-up question. Regardless, I thank you for the response that you've already provided.
Update: The PC components in the original pcpartpicker list were indeed successfully ordered for and received by my friend. He's extremely excited about his Intel core i7-10700 and AMD RX 5700 XT build. Thank you once again for quickly reviewing and responding to my posting.
