What Lemmink just said is the absolute 100% correct way to run a B PPC card in a A1200.
And I'd only add that making a tower solution could solve many heat/power problems.
I made my own with a big old AT server case and it
worked out great. You just need some beer, dremel tool, ultra violence, heat, friction, a bit of cussing and
bleeding (you will cut open your hand) and soon you'll emerge on the other side, A1200Tower land.
BTW, my fan blew up too, everything still works perfect without it.
:-D
