My first build that I have ever done and honestly I'm pretty proud with how it it's come out so far. I am desperately trying to find a better GPU (Hoping for a RTX 3080) because my GT 240 isn't cutting it (I had to mark it as a GT 450 because the 240 is discontinued so its not an option). I take all criticisms and suggestions as I am still learning and I'd love to learn more! I have been told that my PSU won't work with a RTX 3080 but from my research my PSU should work but idk. All suggestions are welcome.

My case is the BGears b-Voguish ATX Mid Tower Case but that isn't an option and BGears doesn't even show up as a brand so I was unable to mark it for my case.
