I've been slowly (over the past month+) gathering the parts to build an additional PC and it's basically done now. Saved a lot of money by using the old (ca. 2016) parts I upgraded away from.
I put Ubuntu on it as a placeholder OS but also checked to see how much of my Steam library supports Linux, and... huh, I'm actually optimistic that I won't need Windows on this box after all. Here's hoping!
