I bought this case last week and want to fit these parts in it: https://pcpartpicker.com/list/rVjkcH. I already tested the Corsair Power supply, and it fits the case. I had a dead z170 pro gaming, and it does fit. But my question is about the standoffs because it only came with x2 standoffs, and I feel like it needs more, but I'm not sure what those black things are. Should I use those red ones before screwing the bolts into the motherboard? If any expert guy could help will be helpful.
