The age old theory behind this goes way back to warped pcb and surface mounted/soldered components. When u bend a pcb, as the components' legs go through the pcb, they have a presence on both sides of the pcb - the upper side ~usually~ has the more bulk - underneath ~usually~ being just the tips of the soldered legs. It's these points where the solder beneath the pcb breaks away from the tracks running around the pcb that they're meant to be soldered to.
If u have a mobo that u know if broken, and are about to throw it away 1000% - bend it and u'll see and perhaps hear the solder coming away. (don't do it to a working one ofc).
What "oven baking" is meant to do it to get the solder to reconnect with the pcb in it's new shape. People are actually doing things similar to this to save xbox360s from rrod/rcod. Working so well in most cases that they're prepared to buy broken ones off people.
Agreeing alot with what luckyboy says too, even with a stock intel cooler, and the positioning of mounting posts, u can feel the pcb of the mobo give far too much when u press on it. Would be handy to have a back plate as standard, and elcheapo plastic thing would do.
