Not shockingly expensive. In Feb 2018 I bought a new APC Back-UPS
Pro,330 Watts /550 VA for GBP126.
I have two Jetway NF9W-2930 industrial motherboards, one of which has
been running Ubuntu Server on my laboratory power supply for some
months and will be my new home server when the new Ubuntu version comes
out in April. I suggest anybody interested searches eBay for this
Jetway board. With a Toshiba 2TB HDD it's only pulling about 1.3A from
the 12V supply. Not bad! And it can easily be set to boot on power up.
So for about GBP200 plus a HDD/SSD, a stick of DRAM and a 12V 2A power
supply you have an extremely reliable low power computer with UPS, USB
sockets etc. that with apcupsd installed will shut down elegantly after
an extended power failure and automatically reboot when power returns.
