i just took another closer look. and measured my memory cooler again bro. ang height sa ako memory cooler mu abot ug 60mm. ang clearance sa dark knight is 35mm so for sure dili jud mu lapaw ang height sa dark knight.
and also, a closer look revealed that by looking at your cpu cooler, the fan clearly overlaps the name of the mobo "gigabyte ga p35-ds3l".
and looking at my memory cooler, it also overlaps the name of the mobo. so sadly, i conclude magka conflict gyud sila in design.
