Well, you're right that an ATX PC is never truly off. But a circuit
that would go truly off, but could power up with a switch like ATX,
wouldn't be hard.

And, as I understand it, an ATX computer that is "off" can wake-on-lan.
I've got no idea how much power an ATX machine draws when "off".
But they also have a switch on the back which is "truly off". What the
OP is looking for would end up being the equivalent of hitting that
switch.
