I don't know if the motherboard uses those caps for timing or for filtering. If they are used for timing, then changing the uF would throw it off. If they are just filtering capacitors, a small change in uF wouldn't be too detrimental I think. But since I am unable to tell from looking at the board, I would try to get the same uF or maybe a tad higher. But the same is ideal.
As far as I know, a higher voltage rating wouldn't affect it too much. It would probably just be a slightly bigger capacitor. It would change the resistance some, I think, but I'm not sure if that would prevent the board from operating.

See if you can find the ratings on those capacitors. I doubt it will be hard to find that exact rating on digikey.
