So you put the stand offs on the either micro atx placements or the ATX placements and then screw those in and then after putting on your GPU, blah, blah, blah ... You then add the screws to tighten the MoBo itself, correct? Also my other confused moments were the Wiring...Is the wiring part in the manual? I keep hearing how it's idiot proof but when I look at ALL those wires on the PSU I'm like "oh, god". And BIOS I heard you're supposed to make some adjustments if you could clarify some of those things or all that'd be amaazing;)
Yes you screw on the stand offs onto the case, install your I/o shield, place the mother board on the stand offs then screw the screws in to secure the motherboard. The wiring part should be in your motherboard manual. Also, this guide will be very helpful for wiring.
