I'm looking for some opinions/advice on a gaming PC I'm thinking of building.
I'd prefer to keep this an AMD build. I have the 2 hard drives because I plan on using them in RAID 1 and using 1 as a safe backup drive.
I mostly want to make sure everything will work right with each other (everything will fit, there's enough slots, there isn't a huge bottleneck issue, etc)
I could probably go $100 more than I have here.
As this is a first build there are probably some amateurish mistakes.

Current build:
