Thanks.
Here I'll reply to both of these very helpful replies:
The server closet was created with ample power available - and the phone system has a very long run UPS, extra surge protection and surge protection on all POTS lines (we get some bad T-storms here as well as lots of dirty power).
Failure & impact wise, I am currently leaning strongly towards the Obi-based FXO solution for all the exact reasons which Mr. Addams provided above.
I can easily set up a PBX PC of good, solid h/w, have 5 Obi boxes actively in use, and a spare also - and network capacity is as easy for this as adding a switch and some cabling.
The main hurdle I've tried to explain is that of choosing the types of h/w and the specific bits themselves in order to get the best reliability for years of good service without my having to drive a couple of hours to fix (or replace...) the system regularly.
I do most of my work remotely and the PCs in this office perform very well with just routine attentions from me via VNC.

One point of advice: If you buy a multiport FXO card (or two), or a single gateway unit, you have a significant impact if it fails.5 Obi 110 units will be about the same price, but if one fails, the impact is low. You can afford to keep a spare. On the other hand, OBI's don't have hardware echo cancellation. I've not run into problems, but I've not used them much in this manner.As you've found, there is documentation on the web as how to use the Obi's FXO and FXS ports with asterisk.ESX is simple to use. 30 minutes and you'll have your virtual machine up and running. But, it is probably overkill. Just grab an old PC and run your PBX on on it. Keep a spare around just in case.
That is a route to go, but you still have the issue of multiple network connections and power as well. Most small server closets, in my experience, power is not a luxury. If anything, if external was chosen, I would do two 4 port gateways and evenly distribute the lines.
