Its cool that you tried most people would not even attempt to do something like that! Now you know you can do it.
Every motherboard has a certain socket and that socket usually only fits one or two processor styles from one manufacturer.
Actually if your going to build another one first decide on the processor you want then read the requirements and build from there.
Its really not that big of a deal if you can read and comprehend you got it!
I didn't build @lovenfreedoms threadripper because mining has made GPUs so expensive I could not build it myself cheaper then Cyberpowerpc could build it for me. She has 2 -12 GB GPUs SLI it saved me 1500 dollars and my time to let Cyberpowerpc build it.
Yeah, I heard GPU prices are through the roof because of mining. I probably won't ever build another computer again lol. It hurts my brain!
