I have Antec 900. It's great. However, it doesn't have external 3.5" bay, only internal. I also have a memory reader , that is 3.5" internal reader from Rosewill. How do I do this? Some kind of 3.5" to 5.25" mounting kit but then what about the face?

Pretty much you're sol other than putting it in the 5.25 bay. Maybe take one of the covers and cut out a hole and use it as a faceplate.
