Hi, I'm very interested in your T-am complete build up set. But I'm a total newbie and don't know much about electronics!

From your picture, I saw that the SMPS has a metal mesh as cover. But the holes on the mesh are quite big, it seems dust can get into it quite easily! Can U use metal mesh with smaller holes?

Pls don't mind if I sound a bit silly 'cause I'm so used to those mini hi fi set. Thanks!
