I have built atx desktops, but am considering a mini itx. possib ly with one of those pico power supplies, and an intel 2120t for low power. this will just be for microsoft office stuff and web browsing. I am not a gamer. I understand there is often not a case fan, and if I use a ssd I think the whole thing should be ok with just the cpu fan. anything I need to know before getting myself into trouble?
