I made my standoffs correct, everything works. Computer is booting, using it currently with no problems. I just used the wrong screws, some of them are a bit too long and pop out, however the motherboard is secure and stands on the standoffs.
I just wanted to know if this is okay, the motherboard isn't loose or anything and it seems to work fine. In the long run, will I have issues? It works okay now, but I don't know if everything will just screw up in the future.
