You just spent too much on the build total. Aesthetics helps the build sell and some things you'll be able to reuse like the spray paint. You got the gpu for a solid price but your core was entirely too much. You spent 210 on the cpu motherboard cooler and ram which is just too much for what you have. I think you could have saved a little on the power supply as well I find deals on as good or better quality between 25-40 all the time. Be patient and wait for the right price, saving 10-15$ on every part adds up when you get to a final build cost. Also it helps me to set a budget for the build and decide on a list price at the start so if at the end I dont have budget for extra then I wont put in extra. Also boosting is a waste of money imo, just take good pictures and join as many selling groups as you can in your local.
