I just built my computer about a week ago, and it was my first time doing so. There were some problems along the way, but the computer eventually got built. However, some of the problems that I encountered still bothers me. For example, when I plugged in my graphics card, the screw holes of the card and the case's screw holes on the PCI expansion slots, did not line up perfectly. They were off by a few millimeters. I had to push on the back of the case a little bit to get them aligned. I was wondering if this was normal. Also, I could not line up my motherboard with the standoffs at first. I had to rip off the padding on the I/O shield in order to get it to fit. I was wondering if the padding served a purpose. I'm pretty sure the standoffs were in the correct position (the NZXT S340 makes it very clear which ones I'm supposed to be using).
