So a couple of years ago (about 3-4 years ago) I remember I used to watch this Youtuber, he mostly played console but started gravitating towards PC. I remember in one of his videos he mentioned some website that was kinda like PCPartpicker, where you pick which parts you want for your PC and pay for it, and then they build it and ship it to you. Any of you guys know the name...even if you can't find the exact website, do you know of any website like that where you pick the parts and they build it for you and then ship it?

I'm located in the U.S. if it matters.
