Most of it looks really good, but i have two suggestions:
Secondly i'd probobly upgrade the upgrade the PSU from 80+ bronze to 80+ gold as a 500 watt PSU is pushing the limit a little bit especially if it's a bronze one. If you get a gold one instead it certifies that you'll have 90% of the wattage you've payed for instead of 80%.
That's not how it works. No matter what certification a 500w PSU will provide 500w. No matter if it's bronze of platinum. The certification just tells you how many energy it needs to consume to provide the 500w.
So you just save a few cents if you go gold instead of bronze.
It's no indicator of bad quality or less watt.
So your PSU is fine. It's a Tier 3 unit referring to the tom'shardware PSU tier list and the definition fits your build so just leave your build as it is.
Here is the definition:
"Still safe to use and stable, just lower quality components. Not really ideal in serious overclocking or super-high load situations, such as a Bitcoin mining rig or a high end gaming system."
