How about backups? Backing up 2-16TB needs a bit more planning and design.

Well there's off-the-shelf x86 desktop PC hardware, and there's
off-the-shelf x86 server hardware.

In my experience for name brands it's about 1/7 DOA for the former, and 0
for the latter. There's a big diff in dependability. The latter tend to
keep running for many years, typically being retired for no fault of their own.

Then there are users who stick no name memory into their servers or "servers".
