I’m currently building a pc I have all the parts and my motherboards is set up ready to be screwed in so I can continue putting the rest of it together. However my pc case , Obsidian 500D RGB premium mid tower case) hasn’t come with any stand off screws at all the only screws I have are for the icue h150i cooler and 3 tiny screws that came with the motherboard. Can anyone help me out with some information as all I can find is the same stuff that the case come with standoff’s and screws (which it hasn’t).
