What to Look for When Shopping for a PC Case for Less Than $100 

Before you throw your hard-earned money at the first best PC case under 100 you come across, it’s important to consider a few factors. I want you to make the most informed decision in your purchase. To ensure you do just that, we need to cover a few aspects of PC cases.

Let’s look at them one at a time so you have a better understanding of what goes into a new PC case. This will allow you to better research valuable information easily and efficiently. Soon, you’ll be enjoying all the perks that a PC case has to offer.

Check Your Components

The first thing you need to take into consideration when shopping for the best PC cases under 100 is the type of motherboard you’re using. As you probably already know, components come in all shapes and sizes. It is therefore important that you check to see exactly what you’ll be transferring into your new PC case.

You want to confirm the models of things like your motherboard, graphics card, sound card, and cooling system. Will the best computer case under 100 you are interested in accommodate these things? You don’t want to wind up with something that is too small (or possibly even too big) for your current setup.

Something else to consider is the hard drive or hard drives that you plan on putting in your new case. Does the case in question have plenty of bays to support all of your components? 

A little data goes a long way. Make a list of everything you’re working with and you’ll have a much easier time selecting the right PC case for your needs.

Cooling System

A good cooling system is needed to ensure that your new setup runs smoothly. This is especially true if you have a lot of internal components. A crowded PC without optimal airflow can spell trouble.

If you prefer getting the best case under 100 with tempered glass, just remember that they often need more fans for the best performance. By design, they don’t allow good airflow, and can get hot inside the case really quickly.

A hot PC can lead to shutdowns, ruined hardware, or even fires. Make sure you take the time to research each case to ensure that is the right fit for your needs. That being said, even if it isn’t, a little extra work can transform it into the case of your dreams.

Now, let’s look at a few more things you should take into consideration. This will help you weed out certain cases and narrow down the ones that will benefit you the most.

Features: 

  • Excellent cable management that improves convenience

  • High-quality materials for increased longevity

  • Lots of room for potential expansion

  • Friendly interface for easy access

  • Included fans for basic cooling

With an amazing price and stellar build-quality, the Phanteks P400 is an excellent buy. Made of a combination of metal, steel, and tempered glass, you’re getting supreme durability that’s affordable and manageable. 

Upon opening the Phanteks P400, you’re introduced to a wide open interior. There’s plenty of room for components, although it is missing an optical bay drive. The bottom of the case is equipped with the power supply cover. 

You’ll also find a convenient cable management cover. This serves to keep all of your pesky cables out of the way. I like that there is room for easy SSD installation. It’s a well-thought out setup that deserves praise for its effectiveness.

The casing itself is quite attractive. The top is adorned with a simple user interface that includes the power button, the two USB 3.0 inputs, a headphone jack, and mic, lead, and reset. You can also control the lighting system that comes with the Phanteks P400 case.

The beauty of this lighting system cannot be overstated. It boasts 10 RGB colors along an LED strip that wraps around the front of the case. When turned on and glowing at its brightest, this addition makes the P400 the winner that it is.

You can even expand on this lighting system if you so desire. The pricing to do so is quite reasonable, and only adds to the P400’s illuminating allure. By incorporating additional lighting, the P400 becomes one of the best gaming PC cases under 100.

With both a front and rear fan system, you get basic cooling right out of the box. However, you will likely want to upgrade this with your own robust cooling system at some point in time. This is especially needed if you are packing in a lot of hardware.

You’re getting a truly remarkable PC case that sports many premium features at a budget-friendly price. There’s plenty of room for growth, and the interior layout is a breeze to work with.

To say that I am pleasantly surprised would be an understatement. The Phanteks Eclipse P350X knocked my socks off with its compact design and sleek aesthetics. But what was most amazing to me was learning of its incredibly affordable price.

You’re investing in a solid and sturdy PC case that looks like a premium build. From its steel body to its awesome RGB lighting, the P350X is one heck of a great buy. 

A tempered glass panel makes up the left side of the case. As you have likely already gathered, you will probably need to invest in an additional cooling system because of this. That being said, its aesthetics are stunning, to say the least.

To say the most, the P350X delivers many of the same attributes that you would find in a high-end model – but at a fraction of the cost. Sure, the size is a bit on the smaller side. But for those who aren’t concerned with rapidly expanding their setup anytime soon, this case is the perfect companion.

I like that it is compatible with ATX, mITX, and uATX motherboards. There is a good amount of storage space, as well. The front can be loaded with two 3.5-inch HDDs, along with 3 SSDs. 

You’ll find that there are two integrated USB 3.0 ports, as well as headphone and mic jacks. What is even more impressive is the built-in control that adjusts the RGB lighting to your liking.

This LED lighting system encompasses the front of the case, as well as below the tempered glass. It adds a whole new level of attraction that is often found only in high-end cases. This lighting makes the P350X one of the best gaming cases under 100.

The only potential drawback is that of a single fan. That being said, airflow is most excellent in the P350X. There are a litany of vents to allow for optimal cooling throughout the case.

And I would be remiss if I didn’t mention the stellar cable management found within the case’s interior. It makes all the difference when trying to install all of your hardware into this rather compact unit.

Pros

  • Beautiful lighting system
  • Well-placed ventilation
  • Attractive design
  • Budget-friendly

Cons

  • Might be too compact for some

Editor's Rating: 4.2/5

Features: 

  • Incredible noise-dampening for quiet performance

  • SD card reader delivers greater convenience

As the most expensive case among our reviews (but still under $100), Cooler Master’s Silencio S400 is quite the enigma. It isn’t the prettiest PC case you’ll ever come across. In fact, it’s quite boring.

And yet it delivers some absolutely incredible sound-dampening performance. Those looking to hush up their noisy PC will love what the Silencio S400 brings to the table; or computer desk, in this instance.

The all-steel construction ensures that you are getting a long-lasting case that provides exceptional protection. I’m rather fond of the ventilation. Cooler Master positioned it in all the right places, while still maintaining its noiseless operation.

The difference this case makes in the sound department has to be experienced to fully appreciate. A big part of that goes to the inclusion of a whisper-quiet fan system. Rubber padding has even been installed to reduce vibration.

The top of the unit features two USB ports, a headset jack, power button – and most appreciated – an SD card reader. You don’t often find this addition on budget-friendly PC cases. Much thanks goes to Cooler Master for adding this.

The Silencio S400 is a solid investment for those who are more concerned with performance than looks. And perform, it does. The S400 is the best PC case under 100 USD for quieting noisy computer components.

Pros

  • Excellent build-quality
  • Quiet performance
  • Plenty of storage
  • Roomy interior

Cons

  • Somewhat boring design

Tower Size

You want to make doubly sure that the best computer cases under 100 USD you are interested in can accommodate your PC’s needs. But the truth is, you might not require a big tower. Why? Because as technology progresses, the smaller things get.

Storage systems were at one time pretty hefty pieces of equipment. But today, they are a fraction of the size they once were. The same can be said for just about everything else, as well.

Consider getting a smaller tower that works for you. However, if you plan on expanding sometime down the road, a large tower makes a great investment. You’ll have plenty of extra space inside the case to allow for additional hardware, if and when needed.

Conversely, if you own a lot of equipment that needs adequately housed, a large tower will serve you well. It simply boils down to your wants and needs. 

Progressive thinking is highly encouraged. But if you don’t think you’ll ever want to grow your current system, stick with small, compact, and good pc cases under 100.

The other side of tower size is looks. You might have to invest in a bigger case than what’s actually needed if you find one you really like. So let’s move on to the next section and discuss the style of your potential new case.

Aesthetics

You’re probably investing in a new PC case because you’re bored with or hate the look of your current system. Totally understandable, and a big reason most people decide to make the switch.

If your new tower is going to be out of sight anyway, your options are pretty wide open. You’ll also benefit from your search being a veritable breeze. But if you want the latest and greatest-looking PC case, you need to consider the style you’re planning on going with.

Many new cases come equipped with attractive LED lighting and tempered glass. The two combine to present some truly amazing aesthetics. Oftentimes, the LED lighting is RGB, providing you with a gaggle of exciting and moody colors.

Depending on the environment that your new case will be a part of, RGB lighting may bode well for you and your room. It’s a great way to add some more character to your surroundings. And let’s face it, LED lights are cool.

Additional Features/Ports

Aside from lighting, you may need your new case to come equipped with convenient cable management, USB ports, headphone jack, microphone jack, fans, and so on.

In the reviews that shortly follow this section, I will detail some of the features each PC case comes with. Perhaps you’re looking to cut back on noise as much as possible. Or a case with excellent airflow might be what you’re looking for. 

Whatever the, uh, case may be, always double-check each case comes with the features that are important to you. You want your new investment to be advantageous to you, not a burden that’s difficult to work with.

Compatibility Is Key

OK, you have a good idea as to what you require out of the best PC case for under 100. Now it’s time to make sure that it is compatible with all of your components. Ensuring that everything fits is one thing, but the case also needs to be able to accept what you’re stuffing in there.

The main one to keep an eye on is the motherboard. More often than not, it is the reason for compatibility issues. Secondary components include CPU and RAM. As long as your motherboard fits well, everything else should, too.

This is why it is so important to make sure that the size of the PC case can adequately house your hardware. Once you know you’re good to go, you can start planning on making your purchase.

What Are the Benefits of a New PC Case?

Well, aside from looking totally radical, your new case will afford you the ability to build your setup exactly how you want it. You’ll find a new case to often be much easier to work with, especially compared to the antiquated tower you are currently using.

You’ll have room to grow, as well, if you so choose. PC cases are a great investment that cool your components better, too, allowing for better performance. The cooling systems in new cases are often leagues better than what is currently under the hood.

Cost

Are you on a tight budget? No worries, as I have included affordable options that are well under the $100 mark. By knowing your monetary limits, you’ll have an easier time narrowing down which of the best cases under 100 are within your means.

And remember, you can get some really great PC cases for highly-affordable prices. Cost isn’t everything. True, there are some really stellar cases out there that do some truly incredible things.

But I think you’ll find that the budget-friendly entries I reviewed are more than enough for even the most ardent PC enthusiasts.
