Hi Torbjørn,
It's a bit funny because one of the well known DC-DC pioneers are located in norway. The company is called MASCOT and they build high quality DC-DC converters. I bought their MASCOT 9260 with regulated 13.8V output @ 5.8A, but it has a potmeter that can be adjusted down to 12V output. The input voltage range is 10.5 to 32V and that means that it not boot during cracking. My design uses the 55W molex PSU boards that requires 12V +/- 5% and the Epia M1000 mainboard.
By the way I payed around 1700 Dkr in Denmark, but I believe you can get it cheaper in norway because you do not have to pay duty.
Their webside is
www.mascot.no and I believe you can buy directly.
