Stupid question. That standoff that has a pin sticking out of it to hold the mobo in place while you screw. That's ok to leave in there correct? Its not gonna cause a short or cause any issues without an actual screw holding the mobo down?

i left it there with my ATX board and its running just fine. it also help with install, kinda nice.

both sides were male and threaded. though if you want to put a screw in that location then put one of the male/female standoffs in its place.

I have a picture I'll upload when I get home, one side is smooth, other is threaded on mine, I used the threaded side , works fine after some twisting back in with pliers. It also appears to be slightly shorter than other standoffs, I compared with another. That paint is pretty cheap on the inside.. comes off real easy, all the paint where the mobo connects to the built-in standoffs is all rubbed off after only one install.
