This is my first time building a pc so it's quite possible I'm doing something wrong. However, I have the ASUS P7P55D-E Pro motherboard with an Antec 200 case.
My problem is when the rear I/O panel is installed, I can't get the motherboard to line up properly with the standoffs, I need to push it more to the left but the I/O panel is preventing it from moving any further. I took the panel out and layed the motherboard in with no i/o panel and it fits perfectly with the standoffs. What should I do about this?
I am using the motherboard I/O and I installed it first, with as much pressure as it would take, so I assume it's in all the way, but the padding on the back of it is preventing my from lining up the motherboard with the standoffs.
