Is it okay for the side edges of a motherboard to touch the rear/top of the case? The case is small but supposed to fit atx. The case can have a max of 6 standoffs, I have those 6 used, but I had to push the motherboard rearward (kind of into the I/O, towards the rear of the case) with a lot of force to get it to fit. So the back of the motherboard does not touch the case, but the sides edges of the PCB are touching the case. Is that okay? My power supply is being delivered tomorrow. I want to know if it will be okay to plug in.
