Question on fixing motherboard onto casing

[zenitro]

surprised tat they'd not provide all the req'd holes lor. even if can get by, its quite normal to feel quite insecure abt it, like ur now.

wonder only, if those earring stopper, the soft rubber kind, can fit & hold the preinstalled standoff tat can't be secured...

dun know if those earring stopper can help anot but was thinking of putting a nut there to tighted it...not sure if recommended anot since nut is probably going to be metal
