Hi ! I just got a Abit PR5 R2 from a dead board lot and I probably identified the defect.

Here you can see that there's a regulator that's missing (and the other has its cooler missing)

The difference is even more noticeable when comparing with a photo of the same motherboard http://www.win3x.org/uh19/motherboard/show/114

Does anyone have this board ? Can you shoot a high res image of this area ?
