Hi, I want to buy this case, but there are few questions that concern me. This case has one 200 mm, a few 120 mm as well as some optional fans and my MB has only two sys_fan connectors, one NB and one pwr_fan connector.So are those fans plugged to MB directly or is there other power source for them. Secondly, as i noticed the PSU is positioned at the bottom so should I insert my PSU with fan facing upwards or downwards? And most of all will i get a proper air flow in this case? Thanks.
