I HATE playing mobile games but my wife got me hooked on Dawncaster. It’s a roguelike deck builder. I think it’s like $4-5 and no micro transactions but there are expansion packs to add new zones and enemies. I’ve since picked them all up. It’s regularly updated with free content packs and balance changes. The devs are very responsive with the community.
I somehow missed you mentioning Fractal. My point still stands though. I’ve got the original Define XL. it’s more than a decade old and has housed either one or 3 computers of Theseus, depending. So a pretty good ROI based on its lifespan.
It’s not exactly what you’re looking for but Fractal makes some solid, plain black cases. Most of their models can come with or without windows. The Define line is my favorite - they’re very quiet, spacious, and pretty well designed.
