Dell OptiPlex 2.5" Multidisk Cage pour MT 3020, 7020 et 9020 NAS (contient 7 disques)

This design provides the ability to add up to 7 2.5" SSDs or hard drives seamlessly within a standard Dell 3020, 7020 or 9020 MT Mini Tower case. The disk cage installs under the 5 1/4" dual drives at the front of the case by attaching to the 3 1/2" bay mounts sitting below. To facilitate easy replacement of the drives, each is mounted to rails that allow the drives to slide in and out of the cage. The cage is also oriented to face the open side rather than towards the back of the case to ease removal.

You will need to print a mount, one each of the left and right cage s, and two slides for each drive installed. Re-orient the parts as necessary for printing. You should not need s. Once the parts have been printed, tap all 2.6 mm holes with an M3 threaded screw. Don't overtighten while threading.

Assembly is as follows:

1. Open the case and locate the 3 1/2" drive bay below the dual 5 1/4" bay at the front of the case. Note the location of the two mounting holes facing the case cover as well as the screw slide channel nearer the front face of the case on the other side.
2. Remove the front of the case by unlatching the four left side latches and rotating the cover away.
3. Move the USB on the front of the case out of the way by removing the holding screw and sliding it to the left. This should give you clear access to the 3 1/2" mounting bay. You don't need to disconnect the USB .
4. Orient the printed mount so that the flange is facing up and the nose is toward you. Locate the first 2.6 mm hole on the right side of the printed mount, and install a Dell M3 shoulder screw, typically found on Dell included CD drives. Extra shoulder screws are often provided by Dell with their MT cases and are attached to the backside of the front 5 1/4" blank bay face plate.
5. Insert into each of the two deep-set holes on the printed mount a M3x4x5mm threaded brass nut insert. These can be found easily on Amazon. If you don't have a heated iron to set the nut, a vice grip should do the trick (worked for me).
6. Insert the printed mount plate through the front of the case so that it slides into the 3 1/2" bay. Ensure that the shoulder screw attached to the right side of the mount fits snugly into the slide lock within the 3 1/2" bay.
7. With two M3x5mm screws, attach the mount to the left side of the 3 1/2" bay.
8. Re-attach the USB and the front face plate of the case.
9. Take the right hand and insert the L at the back into the mount slot at the rear of the mount. Slide the forward until the hole in the aligns with the brass nut in the mount. With a M3x12mm socket head cap screw, screw the to the mount via the brass nut.
10. Repeat this process with the left .
11. Take two printed rails and mount one to each side of a 2.5" drive with two M3x5mm screws. Ensure that drive's SATA and power connectors are facing the knurled end of the rails. The drives can be oriented either up or down based on what works best with your setup.
12. Slide each drive into the cage using the attached rails.

Note carefully how the rails fit into the s. The drive rails will lock into place when fully seated, and the drives can be easily removed by pulling and squeezing the knurled handles. You may need to work the drives back-and-forth in the cage a bit so that they slide freely.

The drive cage allows up to 7 drives to be installed. If you are building a NAS with multiple drives, given the close proximity of the drives in the cage you may find it easier to connect the drives to your power and SATA/SAS cables by alternating the up/down orientation of your drives.
