removable top

[TheGreySpectre]

I have a chieftec dragon case and would like to remove the top panel of the case bt be able to reattach it. It is currently riveted on, does anyone know what size screws I need If I want to drill out the rivets and replace them with screws

I believe their 1/8th holes. I would tap the holes afterwards with the standard threads that are used for the motherboard screws. What that is i'm not sure.

Standard mobo standoffs are 6-32 NC.
That size will prolly work just fine if you use screws and nuts.
Your sheetmetal is not thick enough to effectively tap.
