Black is as better as it is more expensive though
NH-U12A might fit, its a bit smaller in height 158mm. And i just checked NH-D15 is 160mm and 165mm with fans but if you have tall ram or stuff at the back of the motherboard like i have that stupid plastic thing for looks, it needs more space than 165mm cause fan sits higher
