Do I need to use standoffs in a wooden case?

I'm building an open air pc and I'm planning on screwing my motherboard right into some wood.

I have seen conflicting opinions on the internet between needing to still use brass standoffs in wooden cases or just screwing the motherboard right into the wood. I'd rather keep it simple and avoid using epoxy with standoffs or putting standoffs into inserts. The wooden boards I'm using aren't that thick so at best I'd have to epoxy standoffs into the boards.

If wood isn't conductive, as long as there isn't any humidity in my room (I have an AC unit in the window) and I make sure the wood doesn't get wet do I really need to use standoffs?

I have read that the PSU grounds the motherboard properly as long as it's plugged into the wall (and into the motherboard of course). As long as I keep the motherboard plugged into the PSU and am careful not to touch it...I shouldn't have an issue with it grounding correct?
 
I know I don't want to damage the solder, but can't I just screw it down directly into the wood but not enough to damage the solder?
 
Solder is to soft. Even the softest wood can damage the solder. You could break lose any number of parts on the motherboard. The rubbing between the 2 would damage the bottom of the motherboard over a short time. The motherboard really needs hold up in mid air by the standoff areas.
 
actually it would depend on the wood. If the wood is soft he may need to use custom standoffs. normal standoffs do not dig very deep and my not be able to support the weight of the motherboard when mounted in wood.

If your making a custom case mountain mods does sell "motherboard trays" this can make it much easier. Otherwise mybe use a combination of a long treaded screw, hollow rod for a spacers and a nut to secure the motherboard.
 
The motherboard is going to be horizontal, not vertical. Would I still need to use special standoffs in this case?
