I have been using a modified battery charger for many years : http://www.mp3car.com/vbulletin/powe...wer-house.html

I really don't see the point of regulating the voltage only to have your power supply regulate it again, unless you have one of those crappy Morex or pico-itx supplies that passes the 12v straight through without regulating it.
