Parts that can be reused
https://pcpartpicker.com/user/Havokmoobii/saved/fCzp99 Looking to upgrade CPU, MB, RAM, and PSU. Also looking for Recommendations on the remaining parts for potentially building a second computer (about the same or slightly better than it currently is) from the remains, but that is low priority.

Do you need an OS?
Nope.


Do you need peripherals (e.g. monitor, mouse, keyboard, speakers, etc)?
Nope.

A guildmate sent me a list of parts as his recommendation. Thoughts on those? https://pcpartpicker.com/list/ZBf4j2

Thanks for any help!
