This is a single PC to use for gaming and streaming, and was built in November, 2018. It was built locally by PC Parlor (http://www.pcparlor.com/), and is solid as a rock. It took three months of researching every part, down to the extra case fans, but in the end, it runs everything swimmingly, is quiet, doesn't get a lot of dust, and is super stable. It's likely the best PC I've ever owned.
This runs Windows 10 like a champ.
This part likely gets more usage than anything else, and it's amazing.
Wonderful sound even from modest speakers.
A gorgeous, gorgeous monitor.
For three different monitors, these were wonderful.
