Well, I guess when you have that many it is easier to forget
. I would recommend buying them pre-made. You will have a better quality product and not worry about them falling apart. If it bothers you enough, then it is worth the cost.
EDIT: My case also has filters on it's intake grills. I don't use the one on the bottom of the case however. The side panel has one of the steel filters like on the xoxide site, and the front fan uses a (nylon?) mesh like most of your standard filters that you wash out with water. Both work well, and speaking of this, I need to clean them out
