Simple. A "good" amount of upgrades to Carbon that's gradually helping it become closer to its final state.
What's Carbon? A system I built with one important feature. Time. You can build a "overkill" system for a small child, but here's the thing. Will they really use all of it's power right away? Probably not. I didn't feel it was necessary to have so much horsepower right at the start. I wish I did but budgets didn't allow it.
I saw it as this. I found out what I wanted to do back then and then I went off of that. Early summertime of 2017, I was only planning to do only a very small amount of video editing and eSports when early 2018 would come around, seeing how my game library wasn't all too big at the time. So I picked out two things before the rest. The chipset and the CPU. X370 so I would not run out of upgrade headroom in the long run, and a decent CPU, (which is still performing spectacularly at the time of writing), that would get me through whatever without a surge of distracting lag. I still have both. In a later major upgrade I might get the CPU replaced however, just not anytime soon. For the motherboard, I won't be needing the advantages or aesthetics of the X470 boards just yet.
I then went to choosing a GPU off of the used market, getting a RX550 @ 2GB of VRAM. It held up fine. Still had no big games to throw at it (at the time) due to money allocation to the PC rather than games. Then RAM, then everything else. Little things that wouldn't matter all too much. The now rather cheesy explanation for those is here: https://pcpartpicker.com/b/kwCbt6 ; enjoy.
As for this build list. She's still getting an upgrade or two here and there, but we are still long ways away from Carbon's final form.
Until then! Yes, I am open to comments and what not. I know I'm not perfect.
