This design keeps dust out while providing an enormous amount of cooling for the entire motherboard.
However, cleaning it is annoying. One must unscrew the inner mesh and its panel, then pop the panel out of a number of tabs. Once that’s open, one can carefully clean it. It took me approximately 20 minutes to clean it.
Check out the picture for the amount of dust which had accumulated since mid-March when I reviewed it for ThinkComputers.
