I dunno,  it would have to involve modifying an existing setup to work with
a 12V input...  There's barely enough space on the rear panel of the one
ATX box I can look at here,  and of the ones I've seen the inside of there
isn't all that much room in there either.  The one that died on me a while
back not only had a board in the bottom but also a smaller board mounted to
the tops of the two heatsinks in there!

Some of the older AT-style power supplies sure seemed to have a lot more
room in the box.  (Looking up at the one that's currently running the BBS
machine in a full tower...)

What do you think it would take to make this work?
