No need to remove the harddrive cages. I was able to place the H/C in the bottom. I did remove the bottom fan/harddrive cage and fans. The plan is to remove all the sheet metal where the two fan cages were and replace the metal with solid sheet metal. I then will cut the metal for a 120mm fan intake. Also I will make a slide style filter tray. Of course everything will be hidden behind the plastic front grille
