Counterpoints: - Specs are too limited for my needs (storage capacity for backup / home NAS purposes; compute power for local AI work; throughput for local high speed network traffic shaping; etc) - can't upgrade over time (right now I'm averaging 15 years for my boxes, with incremental upgrades like storage, RAID adapters, memory, CPU etc, and I don't need to go through the days-long hassle of reformatting, reinstal…
I feel like I rarely upgraded anything except GPU and storage. And GPU's are not needed for a server.
Enclosure means easy storage upgrade and I can always reattach the enclosure to another machine quickly. Might even install OS on the enclosure, then the whole setup will survive compute upgrades until the predominant architecture changes.
