I just had a set of 3 paralleled electrolytics more or less explode on an nVidia video card. Some further poking around, however, revealed that they were damaged due to a drain-source short in the buck regulator they were supposed to filter. The three 5V caps ended up with 12V across them. So it isn't *always* the electrolytics that are to blame!
