+The backplane that connects 2.5" storage drives to the system upon insertion can be independently replaced using the steps below.
+
+**Tools required:** Cross-head (Phillips) screwdriver
+**Time estimate:** 15 minutes
+**Difficulty:** Easy ●
+
+### Steps to replace the included 2.5" backplane:
+
+1. Follow the steps above to [remove the 2.5" backplate and any installed 2.5" storage drives](#addingremoving-25-storage-drives) and [remove the right side panel](#removing-the-side-panels).
+2. Unplug the SATA and power connectors from the back of the 2.5" backplane.
+
+
+
+3. Unscrew the four screws holding the 2.5" backplane into the 2.5" bay.
+4. Remove the old backplane from the 2.5" bay by tilting it until it fits out the back of the bay.
+ - Alternatively, push the backplane out the back of the computer.
+5. Insert the new backplane into the 2.5" bay.
+ - The backplane should be oriented so the port labels are upside-down.
+6. Screw the new backplane into the 2.5" bay.
+7. Plug the SATA and power connectors into the new backplane.
+ - The order of the SATA data cables shouldn’t matter as long as your operating system and software is configured to address disks by UUID (e.g. `/dev/disk/by-id/...`) instead of by letter (e.g. `/dev/sd_`).
+ - By default, the ports connect as follows:
+ - `DATA0` (on the left) connects to `SATA3_A2` (on the left, farthest from the motherboard).
+ - `DATA1` (on the right) connects to `SATA3_A1` (on the right, closest to the motherboard).
+ - The 4-pin Berg adapter connects to a 4-pin Molex cable, which connects to the [power supply](#replacing-the-power-supply).
+
+## Installing an additional 2.5" or 3.5" bay:
+
+In addition to the included 2.5" bay, you can also install an additional 2.5" bay to add two additional 2.5" drive slots (for a total of four). Alternatively, you can install a 3.5" bay to add two 3.5" drive slots (in addition to the two included 2.5" drive slots).
+
+**Tools required:** Cross-head (Phillips) screwdriver
+**Time estimate:** 15 minutes
+**Difficulty:** Easy ●
+
+### Steps to install an additional 2.5" bay:
+
+1. Follow the steps above to [remove both side panels](#removing-the-side-panels) and [remove the front glass](#removing-the-front-glass); also remove the new 2.5" drive bay's cover (if installed).
+2. If it's not already installed, insert the 2.5" drive backplane into the 2.5" drive cage, then screw it in from the back.
+ - On the interior of the cage, the backplane's larger side gap should face towards the closed side of the cage.
+ - On the exterior of the cage, the orientation of the backplane will cause the port labels to be upside-down when the cage is installed in the Thelio.
+
+
+
+3. Screw the 2.5" drive cage onto the front of the chassis.
+
+
+
+4. Connect the backplane to the top two SATA ports on the motherboard, and to the power supply.
+ - M.2 Slot 3 will be limited to PCIe NVMe Gen 3 speeds while either of the top SATA ports is connected.
+ - The SATA ports are located behind the dedicated GPU (if installed), but can be accessed from behind using the cutout behind the right side panel.
