Also anecdotally, I’ve been running 12th gen Dells (over a decade old at this point) for several years. I’ve had some RAM sticks report ECC failures (reseat them), an HBA lose its mind and cause the ZFS pool to offline (reseat the HBA and its cables), and precisely one actual failure – a PSU. They’re redundant and hot-swappable, so I bought a new one and fixed it.
