Not too much. they are only 1/8 in long. they dont grab until you get them about an inch apart. my HDD's are in the back of the compartments so that shouldn't be a problem and you would need a pretty powerful field to disrupt you PS.
My wife's csx case has stronger ones right along the side next to the bays and they don't seem to bother anything.
