Antec P-180 question about PSU & Studs

[Exibit]

Hi guys I have a quick question about my Antec P-180 case - sorry if I am being thick

First question I have just fitted my Corsair PSU now should I have the fan on the PSU blow down as it is in the picrure or turn it upside down and have it blowing up

Next questions the studs on the rear of the case are these the stand offs for the motherboard or do I screw the brass stand offs onto these - also any other tips on this case would be great.

Thanks for that, I will leave the PSU I think seeing as it will not effect performance,

As for the standoff's for the mother board - I thought they were but when I saw the brass ones in the bag I thought they must screw onto those in the picture


Thanks for taking the time to reply very good of you

My PSU is modular m8 so should not have too much of a problem with cables

Thanks though
