But yeah, if you can't or don't want to seal your case and put dust filters on every intake, go for positive, that will make your live easier.
Yep! My current rig right now is on a Corsair Obsidian 350D, got 2 dual 120mm radiators inside (top and front) with push/pull configs. well the front has the Push/Pull config and the top only has push config. I have 1 intake fan on the rear part of the case with a filter. It does the job but man, cleaning the filter every week, I am just amazed on how much dust it takes.
i might use 2 200mm fans for the bottom part of the desk. one on each side of the cover and the middle part of the cover will be mesh. The top cover of the desk, I might go with grabbing a 1/2" acrylic sheet with the same dimensions of the cover. The cover for the top, which was just a plywood, got kinda flimpsy since I made a huge window in the middle of it. That might not be sturdy enough to handle a 27" monitor on top. If I go with the acrylic sheet, I really don't have to make another window on it since it's already clear. So I might go with that. Well, we'll see if I could find a cheap one on kijiji.
Thanks for the suggestions and tips iFreilicht!
