I'm building a PC with a NZXT havik 410 and G.Skill Sniper RAM. I'm worried the ram is to tall, will there be any room or should I buy new RAM(the ram is from my current PC)?
If you have enough room in your case then you can just nudge the little rubber straps that hold the fans on to accomodate the RAM, as it isn't exactly the tallest RAM in the world. Otherwise, you may have to consider either switching RAM or switching coolers. Either one would suffice for solving the problem.
