After putting together PCs 30 years ago, this is my first go a modern gaming PC.
Thanks to pcpartpicker, I had no compatibility problems with the main parts. The hardest thing was to get the led fans light up correctly. I ended up with a couple of spare parts (some fans and a lightning controller incompatible with my setup), and with a ton of experience with corsair cooling products.
Building it with my 11 year old son was an incredible if sometimes nerve-wrecking experience. He got to name the build, and he decided on `cupcake.' Don't ask me why.
We currently run Destiny 2, Fortnite, Subnautica, Cuphead, and Minecraft. The machine runs these games around or above my monitor's 180Hz refresh rate while maintaining low noise and awesome looks.
