ahh... yes, you screw it from the inside, because logically, the end of a screw looks better on the outside of the case than the start of a screw
oh okay

that helps a lot! now one last thing. Fan grill. Is it possible?
no I don't think so, the fan grilles can only be done at the back i think, cause there are special dents by the back exhaust that allow the grilles to be inserted and not look out of place, also even if you could, that would restrict teh air even more as there will be a mesh AND another grille blocking it so the fan won't draw in as much air as it should
