When I was trying to build one of my computers some years back, I only had two options at hand – either to buy a full tower case, or a mid-tower case. But a few years later, everything changed.
Now we have plenty of different cases to choose from. You have the privilege of buying small PC cases that you can carry everywhere as easily as you would carry a suitcase – a feature that you just cannot get when you go for a full or mid tower option.
That being said, small cases usually fit only small parts. People who want a compact build normally look for small computer cases that don’t waste a lot of their space, but fit important components as well. PCs can sometimes take up a lot of room and this can end up becoming quite inconvenient for some users. That is why you need to go for something small yet powerful enough.

2. Corsair Carbide 400C – sub a mid-tower case that has a compact design and full size capabilities
Corsair has been an avant-gardist when it comes to computer cases. It has given us a lot of ground-breaking cases till date, and the Carbide 400C series is one of them.

Whatever Corsair comes out with, I like. However, I have tried to give you my most unbiased opinion this time. The sleek jet black design is attractive from the outside, but that is not the only quality of this case. Despite its relatively smaller design, the case comes with features of full sized cases. It allows for future upgrade compatibility since it can handle a full-size ATX motherboard along with multiple video cards for SLI and Crossfire configurations.
If you are clumsy, don’t worry! The all-steel build makes the material very durable in the long run. The full side panel window provides a great view of your components. The case has room for radiators in the back, top, and front so that you can fit in your liquid coolers. The drive cages are placed in such a way that the airflow from the front is not obstructed. This allows for a direct airflow path and makes sure your system is cool and quiet. Two 140 mm Corsairs AF series fans are included along with the case. You also get room for additional fans.

The minimalist design is eye catching and the features are incredible as well. However, if you are looking for something size-efficient, the Corsair 400C might not be a good option. The mid-tower size can be large for some and the cost is also heavy on the pockets. But if you do not care much about size, I would recommend it.

- It has a mandatory cable routing design
- The case supports Strider Plus PSUs up to 1000W

Designed after its predecessor, the Silverstone Sugo SG09, the SG10 is a revolutionary little chassis. Unlike the SG09, the front panel now utilizes a 7 mm thick aluminum with a fine filter hidden beneath it. This has increased its minimalist appearance. This SFF is only 23 liters and it has retained all of Sugo SG09’s features.
Along with those features, it can now house standard size components such as ATX power supply, micro ATX motherboard, full tower CPU cooler, and dual 13.3″ high-end graphic cards. It also supports mini ITX compatibility. The case fits a Micro ATX and still provides room for an optical drive. Not only that, it has great air circulation as well. The case might not be the smallest ITX case around, but it is definitely one of the smallest MATX cases out there.

The case has three 180 mm fans along the bottom of case which help the distribution of air, providing incredible air cooling. It has no cables on its four sides whatsoever, but the front side panel consists of updated USB 3.0 port and audio ports.
The FT03 supports standard ATX power supplies. The case provides the user with enough room to work inside, and even supports some large video cards. The standard model of this case accepts a regular PSU. The dust filters on the case can be removed with no trouble, thus making maintenance easier. The case also consists of a hot swap bay for quick data storage needs. If you are on the lookout for something small and efficient, you can find this chassis for around $160 online.
8. Rosewill Cullinan – compact chassis that can fit lots of powerful hardware and liquid cooling setups
Unlike other cases, this case from Rosewill uses glass as a material on three sides. Because of it, some might think it to be fragile, but it maintains its ability to fit in other important components quite boldly.

The design of the chassis is not very striking since the glass limits the possibilities; but the clean and simple appearance makes it quite classy in my opinion. The four LED-equipped fans make sure the system remains cool and maintains its temperature. The Cullinan also supports up to two 360 mm radiators.
The case also has magnetic dust filters on the top and at the front. These filters can be removed without any trouble and are washable as well. The conventional filter under the PSU bay is the same. The case provides the user with seven expansion slots. Easily removable thumbscrews hold each glass panel in place; and in order to get access to the interior of the case, you simply need to undo them. The chassis does not support any external 5.25″ drive bays. However, it does support two 2.5/3.5” drive bays and three 2.5″ internal drive bays. You can find this case online for around $110.
9. BitFenix Pandora ATX – unique style that can house even full sized hardware

Like its predecessor, the Pandora ATX also comes with a unique design and an LCD screen. It has bigger dimensions which allow for liquid-cooling systems and it has all the required mounting options. The case has steel side panels making it sturdy and more durable. There are some missing bays in the front, but the interior looks traditional and clean.
A shroud covers the PSU bay, and the case also provides the user with the option of three hard-drive placements for either 2.5” or 3.5″ drives. There are four additional 2.5″ plates on the motherboard tray, and a 2.5/3.5″ variant can be found on top of the shroud. Thus, the total number of drives you can fit inside this case reaches up to eight – which is quite impressive in my opinion.
The case comes with two fans, it provides the user with lots of room, and it also supports liquid cooling. The finishing touches are kind of rough on some parts, but despite this visual downside, the Pandora ATX makes a good case. You can find it for around $113 online.
10. be quiet! Pure Base 600 – a gem for those opting for silent builds

This means the case can support up to eight devices of similar nature. The case can hold radiators up to 360 mm in the front and top. This enables liquid cooling, but you will have to forgo the external drive bays.
Cable management can be an issue, largely due to the location of the grommet equipped openings. The chassis is compact and is has less room inside. The case comes with retail-grade Pure Wings 2 fans. You get a total of around US$22 for free on the fans. Pure Base 600 also provides you the ability to control the speed of up to three of these fans. You can get this case online for around $100.
Before buying a case, you need to pay attention to some very important things. Some of them are featured below:
1. The difference between full ATX, micro ATX, and mini ITX
ATX is the most popular form factor amongst users nowadays. The dimension of a full-size ATX board is 12 × 9.6 inches (305 × 244 mm). This allows many ATX chassis to also accept micro ATX boards. The maximum size of a micro ATX motherboard is 9.6 × 9.6 inches (244 × 244 mm), which is 25% shorter than the ATX size. Mini ITX on the other hand is the smallest out of the three at 6.7 × 6.7 inches (170 x 170 mm). ATX has seven expansion card slots, micro ATX has four, while mini ITX has one. The ATX is the most expensive, but also the one with the most features.
2. Look for a case that conducts proper airflow
If your device heats up too much, it can end up decreasing its life. Therefore, you need to make sure you have a good cooling system in place. Selecting a case with enough fans and vents is usually a good idea. Put your case in an open place. Don’t put it somewhere where it will be blocked.
Fans help in keeping the chassis cool, but they can drive you insane with their loud noise sometimes. If you are one of those people that gets frustrated by loud sounds, you should opt for a case that has been designed specifically for making less noise.
4. Size of the components and their compatibility
Case size and its compatibility with motherboards can vary according to the model. You can find lots of different cases in the market. However, this can often lead to problems when it comes to installing the motherboard. Before you buy a case, find out its motherboard compatibility. You should also pay attention to the size of your CPU cooler and the length of your graphic card to make sure they fit inside your new case.
5. Size of the case:
Like we said before, there are many different cases in the market. Some have a horizontal orientation, some have a vertical orientation, while some can be arranged in both ways. The size of the case might not seem like a big deal to some. But you need to be mindful of its size because it might not fit in the place you want it to. So to make sure it does, measure the case and also the space you are going to place it on.
6. Refurbished cases
Some cases can be pretty costly. So you can check out their refurbished versions online. They cost a lot less and sometimes provide more than you have bargained for.
Choosing a case for your beloved build is always a difficult task. We always want the best for our system, but we need to consider things like money and space as well. So the process becomes quite challenging sometimes. There are many cases available out there. However, not all cases are meant for all people. What suits you might not suit your friend. What doesn’t suit you today, might end up suiting you a couple of years later.
Often times we have an image of what we want in our minds, but we end up neglecting what we actually need. That is where lists like this one come into play. It helps prospective customers understand what kind of case they will essentially require for their build to be perfect. Some of us are into high-end devices, while some of us need to compromise since we are short on cash. Keeping this in mind, we have created this list of the best smallest ATX cases. If you think we have missed out on a case that deserves to be on the list, let us know in the comments!
