Your best PC case under $100 are out there, and are available in all shapes and sizes to boot. You have no shortage of choices, only the question of which case will meet your needs? Fortunately, the sub-$100 market still has a ton of quality options without compromising too much on features and look.

Buying Guides

The first thing you need to figure out is what you need. Do you want a case that has all the options at hand? Do you want a tiny case to sit in a corner of the living room? Do you want something else totally unique and will make everyone turn their head when they see your build? If you don’t have all the answers at the moment, it’s fine. Just read through these factors and slowly you will work your way through everything to know which is your best PC case under $100.

1. Budget

As the title of this article implies, we’ll look for PC cases at sub-$100 price range. However, it doesn’t hurt to see what we get at different price marks. Now, let’s take a look at them, shall we?

  • Elite PC cases over $300: Only the select few are willing to spend this much money on a case. Cases in this price range have everything you need… and beyond. Sometimes they feature too many, to the point of unnecessary. PC cases like Cooler Master Cosmos C700M are for extreme gaming PCs with monstrous specs.

  • High-end cases under $300: A somewhat more affordable price range. These combine the quality of the $200 mark and some insane features of Elite PC cases. For instance, Dark Base PRO 900 features silent built-in fans and RGB lightning.

  • Mid-end cases under $200: These aren’t that far behind the $200-$300 cases in terms of build quality. At $150 you will find many great cases which excels in performance and aesthetics.

  • Affordable cases under $100: The sweet spot between affordability and features. These have been a lot of advancements in this range. Thus, you can find many good options, such as Phanteks Pro M Series and Pure Base 600.

  • Budget cases under $50: The ideal cases for budget gaming builds and office PCs alike. Although they don’t have as many features as above options, rest assured that they can house your components just as good.

2. Form factors

After the price, the next thing on the list should be the size. Determining how big or small your case is important since you want all the components to fit right in. You don’t want to lack the room to plug that GPU in or pay more for the empty room inside your case.

First and foremost, you should check to see whether your case can house the motherboard of your choice. Here is the table of the three main sizes of PC cases and their compatibility with motherboard types:

Motherboard types / Case form factors











As you can see, full tower cases are the largest. It can house more than just the motherboard; you can fit in many extra components into this type. However, they cost more and there’s no guarantee that you will make use of all the space. Therefore, they are far and few within the $100 price range. But you could still find some, such as this Phanteks Enthoo Pro.

The next best thing and perhaps the best option at sub-$100 is mid-tower cases. Most PCs you find in the wild are in this form factor, and for a good reason. They provide the perfect balance between performance and size. They are neither too small or too big and are good for upgrades. Check out Fractal Design Focus G, Deco Gea and Corsair CC.

Last but not least, the Mini-ITX case. They are mainly used by SFF (small form factor) enthusiasts or for home entertainment PCs. Portability is definitely its strong suit, as long as there’s a place with monitors, you can use your mini PC. The downside is that this form factor is truly challenging to work with due to limited space. Some good Mini-ITX cases are InWin Chopin SECC and NZXT H210.

3. Cooling

Cooling is a critical feature you need to look out for when choosing a PC case. High-end system can generate a considerable amount of heat, which is bad for longevity and performance. PC cases achieve cooling through airflow. Airflow in general means letting the cool air in and pushing the heat out of the case.

A case with good airflow would be one with many fans mount points at the top, the front and the rear of the case. For example, this Cooler Master MasterBox Pro 5  supports up to a total of six 120mm fans. Another choice for cooling is water coolers. In this case, you need to make sure that your case has the extra space to house the water cooling system. Phanteks Enthoo Evolv is water cooling ready and hence it is a good choice.

4. Noise

If cooling is so important, why don’t we just install as many fans as we can? The answer is noise. Sounds from your fans, your hard disk drives, optical drives, etc. could make you irritated or distracted.

To solve this matter, you should choose cases with large fans rather than small fans. As mentioned above, large fans spin slower and thus produce less noise than small fast-spinning fans. Next it chooses chassis made from noise damping materials. Optimally, you should opt for those with metal side panels for the best noise-reducing without sacrificing build quality.

The best examples of silent PC cases under $100 are Corsair 110R and Thermaltake Suppressor F31.

5. Aesthetics

This may be the last thing some people would consider, while for others it is the first priority. You don’t want only a nice house (case) to contain all of your furniture (components), you want a nice and beautiful house. When your friends come over, you want them to immediately notice your rig and admire how nice it is.

PC cases under $100 often spot a clean and minimalist look such as this Phanteks Eclipse P400S. It is adequate for a professional working environment and those who just want a case to shove their parts in.

If you prefer something flashier with more personality, thankfully you also have various options. At $70-$100 you could easily find a case with quality tempered glass panels such as Fractal Design Meshify C or InWin 301. You want some RGB lightning? Thermaltake V200 and DEEPCOOL MATREXX 55 V3 got you covered. Do you want something more unique? Thermaltake Core P1 with open frame viewing design certainly will give you plenty of room for creativity.

At A Glance:


1. How do I know I can fit all of my components into my case?

The first thing you should do is research and plan ahead. Aside from the form factors information, you should consult the online or offline manual to check further specifications. For verification, you can use the ruler to measure or estimate how the parts can fit into your case. Careful planning, measurements and research will take you far.

Beside the motherboard size, some other parameters you need to take into account include: GPU length, supported fans size, air or water CPU coolers dimensions, etc.

2. How important is a computer case?

A PC case is as important as any PC components. Here are some reasons you should get a PC case:

  • Presentation: Would you prefer looking at a nice case or bare components without any arrangement? Unless you want to shove your build into a drawer or something, the PC will most likely sit on your desk and in your view.

  • Protection: The case physically protects your components from any outside harms. It keeps the dust, split water or coffee, pet hair, etc. away from your parts.

  • Cooling: Thanks to its closed design, the case helps to maintain the temperature of the parts inside at a reasonable mark. Without a case, your entire components are prone to damage or stealing.

  • Cable management: You want to hide and keep all of your cables in an organized way. What’s the better way to do that by keeping them all in a box or limited space.

  • Ease of access: PC cases often provide you with front panel connectivity. That is to say all USB, audio, DVD drives and other connections are at hand and you can access them easily.

3. Can I reuse my PC case?

Yes, you can. It is even possible to build a new PC with all the latest parts using your old case. You just need to take proper care of your case and it can last for years. The main concern here is can it house all of your new components comfortably. ATX or full tower form-factors are preferable while mini form factors are more challenging for future upgrades.

4. Will airflow on larger PC cases with more empty room be better than on smaller ones?

Bigger cases allow for more fans so they may have better airflow than small cases. Therefore, they tend to have better airflow. However, that’s not always the case.

How the case is setup has a bigger impact on the airflow more than the size of the case. You have to check the number of fans, case layout, cable management, components arrangements, fans positioning, etc. Without proper setup, a big case can still build up much heat and be inferior to a smaller case.

In short, the capability to dispense hot air from the components is what determines a case’s worth of airflow.

5. How many fans should I get in my case?

You bet that the additional mounts or slots for adding more fans will be of use for your PC. As mentioned above, cooling is important, especially in gaming and graphic intensive tasks. So try to get a case which allows you to install at least 3 fans on the system. And that’s not counting the fans for power supply, CPU, and GPU. As a minimum, pick a case with an intake fan for the front, an exhaust fan for the rear and one additional fan.

Final Thoughts

NZXT H510i is our choice for best all-rounder today. This head-tuners PC case is available in a variety of colors and includes integrated RGB Lighting. It offers an enhanced cable management system, three fans channels and USB-C on the front I/O panel. What could you ask for more in a case at the sub-$100 range?

For those who prefer something on a small side, Cooler Master Silencio S400 is the perfect choice. It is made from sound dampening material for better noise-reducing. This small case even has a removable sound dampening top cover with silence fans. If you want something that takes little space and operates whisper-quietly, you can’t go wrong with this one.

And that’s all we have to say about the best PC cases under $100. Regardless of what’s available, it’s up to you to determine your needs and what features would best accommodate them. There’s no right and wrong in choosing the best case under $100, only the one that suits you the most. The one truly unique case for your and your PC build.
