I use this setup with my Intel D945GCLF2 (Little Falls 2) Atom board and it
works fine *but* I think you should I think hook 12V into the 4-pin power
socket near the CPU on a Intel board also regardless, if it's got one (all my
Intel boards have).

If you are really struggling you can get Molex to 4-pin headers that will
adapt the hard disk supply down. I use one on the Atom board because I'm using
a picoPSU with no 4-pin header. Works fine but it is a low power board. I'd
probably prefer a P4-compliant PSU on a modern full size intel board.
