12 Things Every Student Needs to Know Before Opening Their Computer Tower

A computer tower, also known as a case or chassis, is another name for a computer. In other words, it’s the structure that’s connected to your desktop. Towers are important because they hold all the components your PC needs to run – the motherboard, power supply, and memory card, for example.

That said, you’d need to open the tower if you’re experiencing a problem with your machine. In some instances, towers are left open if the computer is prone to overheating. Leaving it open allows air to flow through easily and cool it down. But, on the other hand, it also lets dust in – which is never a good thing.

If you’re a computer engineering major, you might already know this. If you don’t, be aware that many of your classes will require you to learn about (and explain) the intricacies of hardware. In this case, you can google ‘help me write my essay’ and get the grade you want. Read on, however, to get a brief breakdown of how to open a tower safely.

Turn the Computer Off

It’s a bad idea to open your case while your computer is still running. Losing precious information to this would be quite a misfortune.

Therefore, the first thing to do is to save and close all open files and make sure you send that request to EssayService before closing the browser. Exit all open applications and back up data if needed. Shut down your device safely by going to the start menu then clicking ‘power’ and ‘shut down.’

Check Power Sources

Unplug your computer and any other connected devices from their power sources. Capacitors still store electric charges even after you turn off the power switch. After unplugging your PC, it’s advisable to wait a couple of minutes before working on it.

Disconnect All Devices 

Another safety tip to follow before working inside your case is to disconnect all the hardware from it. Some of the hardware you should disconnect is:

  • keyboard;
  • mouse;
  • monitor;
  • network cables;
  • modems;
  • printers.

This isn’t an exhaustive list, of course, so be sure to remove everything else that is still attached.

Maintain a Clean and Organized Workspace

If you’re opening your case, the chances are that there’s something you need to repair or, otherwise, check out. If you make a mistake, it can have serious consequences for whether your device will be functional in the long run or not. To prevent mistakes, keep your workspace organized and clean. Being in a well-lit room is also essential.

Secure Loose Clothing 

Avoid wearing acrylic or wool when working with electronics. These specific fabrics can easily get caught in the hardware and either unravel or disrupt your work.

Ground Yourself

Before opening the case, discharge any static electricity you may be carrying. There are a couple of ways to ground yourself before working on your case. You can use a wrist grounding strap or touch an unpainted metal surface. 

If you opt for the latter, keep periodically touching the surface you’ve chosen as you work. This will prevent the static sensitive components, like the video card and motherboard, from being ruined. Additionally, make sure your hands are clean and dry. Finally, remove all jewelry such as bracelets, rings, or watches.

Mind the Screws

Depending on your computer’s make, you will open your case by either unscrewing or unclipping it. See your device’s manual for instructions if you have problems. However, be cautioned that leaving stray or loose screws inside your case may severely damage it. Keep the screws in a safe place and remember where they’re meant to go.

Apply Tape to the Sharp Edges of the Casing

Before working inside a case, examine its edges and put tape over any sharp edges to prevent physical harm.

Handle Cards and Components With Caution

Static electricity can harm circuit boards and cards. To avoid causing damage, pick up cards and other components by the edges or metal mounting bracket.

Do Not Attempt to Open the Power Supply Unit

Components labeled as “non-serviceable” should be left alone. Tampering with them can be dangerous – not only to you but to your computer as well. The power supply unit, for example, should be replaced, rather than repaired, if it’s damaged.

Observe Electrical Safety Measures

When working with electronics, anything could go wrong. The most pervasive threat is starting a fire. Keep a fire blanket or extinguisher close by, just in case.

Reassemble Your Computer Before Turning It On

Check all circuits and installations. Replace all screws and ensure that no stray screws remain inside your computer. Then, replace the case and connect your devices before powering on. 


To recap, a computer tower or case is the machine that hosts most of the necessary hardware for your PC. Opening it up haphazardly can have dire consequences, so it’s important to take certain precautions. 

For example, turn off your PC before doing anything and hold the components by the edges. It’s equally important to refer to your PC’s manual for instructions when opening your computer tower. Be sure to follow these tips to prevent causing any unnecessary damage.
