Couple of comments and questions...

 a) as shown by a url posted in the thread, PC in mineral oil can work fine.

 b) don't see reason for a video capture card to behave any differently from other components.

 c) sparks/fire (as brought up by someone else should not be an issue, since another essential component, namely oxygen, will be absent from the location of the spark. Also the combustion temperature of oil can be fairly high. I don't know what it is for pure veggie oil, but for example biodiesel only ignites above 120'C whereas fossil diesel will burn at slightly over 60'C.

 d) I don't understand why you want to use white oil, this may in fact be dangerous. I'll explain:
White oil is essentially veggie oil + dishwashing liquid. Detergent is fat + emulsifier. What does an emulsifier do? It allows fat/oil to mix with water. And that's my worry. Why the blazes would you want to add something into your coolant that allows water to mix in the oil?
Water is something you don't want to have any of. When mixed with pure oil, it won't mix, it'll separate with the oil on top and water at the bottom. Easily managed.

So, based on that I would suggest going for pure mineral oil like the other example did successfully, and not use white oil? And please feel free to try and tackle this train of logic, that's what it's there for.

Cheers,
Arjen.
