I wonder if that is true?
Maybe the word "server" is used in two different senses.
I'm thinking of a "home server" - one that links to the internet,
and serves a few laptops on a small wifi or ethernet lan.
This is on all the time, so power usage will mount up.
I think the word server was used historically
for a computer serving a large number of terminals or nowadays laptops,
perhaps in a small business or university department.
In this case, as you say, power usage will come way down
in the order of priorities, after reliability and related issues.

As I said, we are thinking of different scenarios.
I've been quite struck by the fact that my ancient PIII home server
seems quite adequate for the task -
running httpd, ssh, dovecot, collecting email, etc.
It seems to me that a mini-ITX with one SATA laptop disk
should be able to do the work without difficulty.
I'm not sure if a fanless VIA EPIA system, or something similar,
could contain a disk, though?
Regarding RAID, I wonder if that is worth it for such a system,
if one does nightly backups?
I see that disks now are often guaranteed for 5 years,
which must mean the half-life is something more than this.
I would rank other possible disasters - fire, flood, etc,
far higher than this - always as I said in a home setting.
And it wouldn't be that difficult to change the disk if it failed.
