I have a little curve in my motherboard from this side and I can't take my motherboard off to screw it and fix it the pc works fine , is there any problem with it or it's ok to leave it like that
I made 2 top standoff and remain the bottom one i couldn't reach it that's better rightStandoff is not properly screwed in.
Remove the screw and
use needle nose pliers to carefully screw standoff fully into motherboard tray (this can be done without removal of motherboard)
put the screw back in.
If you do not move your pc around, then it's probably fine as is.
