Having looked at the outside of the case, it's time to start adding computers (yes, plural!) to the case and taking a closer look at the internal design. On the left side of the case, where you place the primary computer, there is a drive cage which holds all the 3.5" bays. For now I'm installing a SATA hard drive for the primary system, and a PATA drive for the Mini-ITX.
The cage comes out really easily once you remove the three screws (one on top, two on the bottom) which hold it in place. After that, it's simply a matter of releasing the clip and pulling it out.
The 120mm fan and front cover for the floppy drive slide out as well. If you have a floppy or card reader, you can take out the mesh face plate and replace it with the drive.
The screw holes have rubber grommets to help keep things quiet while they are running.
On the other side of the case is the housing for the 5.25" drives. They have a slide bar on one side which lifts a pin that fits into one of the drive's screw holes. To access the other side of the cage, you need to have the 3.5" drive bay removed. Once it's out, you can access the screw holes and tabs on that side. Remove the screw here that is holding the front plate, then you can remove the screw holding it in place on the other side.
Once the screws are removed, you can slide the bar forward to unlock the drive bay.
You should be able to remove the front face plate, and have the bay ready to insert whatever you are adding to the system.
Here, I'm adding a DVD Burner, which has a nice black faceplate to match the case.
All of the area that is mesh has a thin fiber mask to cut down on the dust that gets into the case. Considering the number of fans you can add to the system, this can only be seen as a good thing.
