Actually I just meant a small cabinet that holds my router, switch,
voip box, and associated UPS. So I just plug the plugcomputer into the
UPS, attach a short ethernet cable to my switch, add a USB drive & done!
I have run BackupPC also on a DNS-323 which is an ARM-based NAS with
just 64MB memory and a 500MHz CPU. It works and while the cpu and
memory are slower & smaller than a plug, it has SATA built-in drives
vs. USB drives on a plug.
I also have a more powerful QNAP TS-219 TurboNAS sitting in a box
waiting for me to have time to play with it -- it has 2 SATA drive
bays, iSCSCI, 512MB DRAM and 1.2GHz ARM processor which makes it the
CPU and DRAM equivalent of a plug but with built-in drives rather than
having to use external USB drives.

But dangling a USB drive has one advantage... you can just swap in a
new drive and rotate your backups without even having to
reboot... (note I keep my ssh keys in /etc/BackupPC rather than in
topdir so that I really only need to have TopDir/pc, TopDir/pool,
TopDir/cpool, and TopDir/trash directories to get it all running.
