I want to build a poor-mans-laptop briefcase computer.
can I just apply a 12v battery to a standard ATX desktop supply at some point in the circuit?
or is there a Texas Instrument DC-DC product for that so I can get a sample?
guides or forums on the subject would help too.
No. They convert 120 VAC to several hundred volts DC before feeding it into the switching power supply.

Look for a tiny board called the PW200M. It's meant for Epia ITX boards, but it probably works on ATX too. If you really want a small computer, you'd do well to check out ITX stuff anyway.
I've run a Via Epia M12000 II from an 80 watt line wart, and a sealed lead acid battery.
