3xLogic Vigil DVRs were available on Shuttle cubes for at least a decade, through several iterations of the machine (they only just stopped selling them a couple years ago). We have some that are a dozen years old, still in service. Some are even running 32 channels total (16 analog, 16 IP).

We generally use Lenovo TS140 Thinkservers with an SSD for the OS and Caviar Purples for the video storage. This setup is as cheap as we can find, yet still highly reliable. The case is a normal mid ATX tower, but that allows for more drive bays and proper cooling.

A long time ago when I was a dealer in the computer world, we sold shuttles, and while like most compact computers it had slightly higher failure rates than mid to full size computer cases, but not as bad as the really compact computers like the tiny workstations from Dell or HP.
Looks like they've since improved on reliability, going by the comments above. Like anything, probably best to always have a couple in stock as whole replacements or spare parts when problems occur since their parts are not as easy to source as say mid and full generic computers.
What class Sub? 16 cameras would be overkill for most, I would think.
I've built many NVR's on the Shuttle platform.
When I was selling Avigilon it was a great option for a small system.
The only drawback was 1x 3.5" Hard Drive with no option for any more.
I stopped selling them when more space was required...
You could also look at the Asus VivoPC if you need it to be really small...
