The guide will cover replacing the Top I/O module on the H3 Flow case.  For this replacement you will need the following:

• A replacement Top I/O Module (aka USB Module)
• A Phillips #1 Screwdriver
• A Flathead Screwdriver

Preparing the Case

To replace the Top I/O module, you will need to remove the following panels from the case:

• Front Mesh
• Right-side Metal
• Left-side Tempered Glass

The tempered glass can be easily removed by using the metal tab in the top-left corner of the panel to pull the glass away from the top of the case.  Once released from the top, lift the panel away from the case.

To remove the metal side-panel can by removed by loosening the two locking screws holding the panel in place, then sliding the panel towards the rear of the case once the screws are loose.  These screws are captive screws and will stay with the panel when loosened.

To remove the front mesh panel, pull the panel away from the case using from the exposed sides of the panel.

With the panels removed, it is also recommended to remove the top-right clip that holds the front panel in place using your flathead screwdriver.

Removing the Top I/O Module

To remove the top I/O module, you will need to remove the four (4) screws which secure it to the case.  Two of these screws can be easily accessed from outside of the case in the top-left corner of the cable management side.

The other two screws will be located on the inside of the case in the top-right corner.

Once all 4 screws are removed, pull the Front I/O away from the case from the cable management side.  There are two plastic tabs (seen to the side of the inner screws) which will hold the I/O module in place.  You may need to use a little force when pulling away from the case to pop the module loose.

Once the module is removed, follow these instructions in reverse to install the new module.  When properly aligned with the two holes in the case, you may hear a loud click.
