I live close to a Micro Center and got the GPU used on /r/hardwareswap, so no, not everybody can make this exact build for under $500 but I am extremely happy with what I was able to put together at this price point.
Built my first computer back in 2016 and sold it to move to an eGPU setup but ultimately was held back in Adobe Premiere and Lightroom by my laptop's 15W CPU, so used the money from selling the eGPU + a little bit more to get a system that is much more powerful.

NOTE:
1. All Prices are in USD
2. Yes, the SSD is relatively small, but for my use case, it is enough to hold Windows and my essential programs. I do have an external HDD that I use for video/photos and games but didn't include it in the price as it isn't necessary to be able to have a usable computer. Everyone has their own priorities when building a system and I valued CPU/GPU performance and aesthetics at the top.
3. Switching out the power supply will most probably be my first upgrade, but the current PSU is handling this system at 3.85GHz @ 1.3V just fine.
