At times, you may find yourself with openings at the back of your computer case mainly caused by the supposed placement of PCI card peripherals which you eventually decide to remove due to one reason or another. While that is not a problem as far as preference is concerned, usual casings do not have provisions to which you can easily patch up that open hole unless you have the screwable blockers to avoid issues such as dust and rodents.
Small as they may, insects such as cockroaches and rats can make their way into the desktop. Once they do find their way into your CPU, you can imagine the problems that they may cause such as:
1. Gnaw on wires
2. Leave a trail of waste that may affect chips and diodes
3. Short your entire CPU like power and other necessary operations that can hamper it from functioning properly.
But while you donâ€™t have to buy the usual blockage parts that are not normally available since people rarely buy them, you can always use the traditional style of using tape to block them off. Rodent intrusion is a problem and you can just imagine what they can do. The only time you can perhaps check if any damage would be done may be when you hear some weird noise or worse, smell something foul.
It may not be a big issue but safeguarding the operating environment of your PC is important. One strand of tape can make all the difference.
