One would not need such stuff.
The load would be, after turn on, pretty constant so no need for that kind of current delivery. I am assuming a board only for audio - no internet connection, printers, simple graphics, nothing but what is needed for playback.
The A123 18650 batteries can supply great wallops of current if required and faster than any Dc-Dc converter if these were utilized instead of any regulator. Instead using a regulator "before" the battery as a charger that only charges to the voltage needed.
One of these days someone will offer such a thing and it will be expensive but there is no doubt what we pay for mass market motherboards is a rather extraordinary bargain BUT you get what you pay for.
If one could get a reliable schematic, not a block diagram, of a motherboard with parts identified one could probably come up with something good. As it is one would probably destroy a few figuring out what does what.

Do you have any evidence to support your claim above? I'm sure they provide 'great wollops of current' but can you point to any measurements showing transient response of these batteries under computer load, vs the best linear power supplies or switching power supplies?
Do a bit of research. You can start a car with them.

So if a battery starts a car, that makes it especially well suited for a computer music server?
Yes this is correct. The ability to start a car is directly related to sound quality.
Merry Christmas...
The battery in this thing must be even better as it not only starts it up, it actually propels the vehicle.
Merry Christmas
