Step Into the Cage
Tool-free case or not, your optical device will go into a cage; a metal box that holds things of that size in the case. The picture at left (from an earlier point in the build) shows where this is in the Sugo with a yellow rectangle. The front of the case will usually have plates held in with little tabs, as shown in the first picture below. These block the slots not being used which not only looks better, but keeps dust from rushing in. Nicer cases may have spring loaded panels that hide the drive but still allow drives to get in and out. This can look nicer than drives that aren’t quite the same colour.
Note that our case, like many others, can fit a 3.5 inch device you want to access from the front of the case (like a card reader or if you still use 1.44MB floppies) in a 5.25 slot using brackets. The brackets and plate are shown in the second pic below for reference, but will not actually be used in this PC.
Remove the plates from the slots you plan on using. Remove the adjacent plates if you want better access, but you will need to replace them when done. Support the drive with one hand while inserting the screws with the other (yellow and red squares, respectively, in the third picture below). Use the screws that came with the optical device. If the device didn’t include any, use the same round headed screws we used for the motherboard. You only need two screws on each side.
