One quirky detail of my build: it has a tiered storage system through FuzeDrive. What that means is I have an 8 TB shucked hard drive and a 128 GB SSD "fuzed" together through some old software by Enmotus that is no longer available for purchase iirc. This means the SSD acts as a cache for my huge 8 TB drive. As a result, I can just install basically any game I want to my massive 8 TB drive without worrying about space, and if I play that game more than once or twice, it'll automatically move to the SSD portion for faster access.
Some ideas:
Is this using used hardware that has a story?
Got an unusual configuration that isn't normally seen (Dual RTX 3070 for example)
