I really like the Node 804 even though the design is quite old - probably close to ten years old now. Fractal Design are still manufacturing it, which is rare for case designs that old.
I recently built a NAS using an 804. I had to fit mine into my server closet which isn’t deep enough to fit a regular PC case, so the 804 fit my use case well.
I’ve only got three drives in it (2 x 20TB Seagate Exos X20 for data and 1 x 14TB WD Purple Pro for security cameras) but I wanted the ability to expand in the future, and I wanted to use a Micro ATX motherboard rather than a smaller one.
A Noctua NH-D15 fits fine, even though the spec sheet says it won’t fit.
