Hey i thought you were driving somewhere tonight and had to put this off till monday or something?
But anyway glad your able to do it and contain the excitement!
The screws your talk of sound like the stand offs to screw the mobo into the case? if so there meant to be done up "hand tight" so that doesnt mean doing them up as tight as you can, but im not sure why your having probs, mine screwed in pretty easy, just take your time
