I live in a small, two-bedroom apartment, and finding enough space for all of my stuff can sometimes prove challenging. This is why I used a small-form ATX case when building my computer.
These cases are designed to hold full-size ATX motherboards and components while still being small enough to fit into any place you wish to put it in. This makes them perfect for those that don’t have a lot of room afforded to them, such as myself.
If you are like me and want to build a computer using one of these cases, then you’ve come to the right place, as we will be taking a look at nine of the best, and smallest, ATX cases.
Cooler Master HAF XB II EVOCheck The Cooler Master HAF XB II EVO’s Current Price On Amazon
The Cooler Master HAF XB II EVO is the picture of what we mean when we say “Smallest ATX cases, as this compact case can hold everything you could ever want in your computer.
To begin, thanks to a compartment-like design, adding and removing any parts in your computer should be a breeze with easy-open access to the inside of your rig. Speaking of the inside of your rig, the Cooler Master boasts the ability to seat up to four HDD or SSD inside of it, along with a full-sized motherboard, giving you much more internal room than it at first appears.
The Cooler Master comes included with two handles for easy movement, as well as two powerful fans. These fans are strong enough to keep even the most intense of gaming rigs cool under pressure and eliminates the need of purchasing other fans.
Surprisingly, the included fans also bring about the main drawback of this case, as the included fans can sometimes become a bit noisy. This can become a distraction to some, which can make you want to replace the fans with your own.
A little noise is a small price to pay for this case, however, as the Cooler Master HAF XB II EVO is simply one of the best, easy to use small ATX cases around.
Corsair Carbide Series Air 540Check The Corsair Carbide Series Air 540’s Current Price On Amazon
Corsair is a name that is well known for its superior computer products. When it comes to small ATX cases, Corsair has an offering that can more than live up to its reputation in the Carbide Series Air 540.
This case is made for keeping your computer cool and clean. This is thanks to its direct airflow design, which helps to keep the most crucial parts of your computer cool when things get intense, and a front dust filter, which will keep dust and grime away from the inside of your computer.
The case comes equipped with three fans to help keep your computer’s temps as low as possible while eliminating the need for buying your own. Also equipped inside the Air 540 is rubber grommets, which help you to keep wires in place and reduce clutter.
If anything can be said bad about the Air 540 it’s how loud the case can be. This may be due in some way to the parts of the case itself, which appear to be cheaply made and easy to break under stress.
If you don’t mind a bit of extra noise then you will find a lot to love about the Corsair Carbide Series Air 540. With the ability to keep your computer safe and cool at all times, you know that this small-form ATX case will keep your computer safe for years to come.
Corsair Crystal Series 460XCheck The Corsair Crystal Series 460X’s Current Price On Amazon
Corsair is a name that you are likely to see pop up on this list of Smallest ATX Cases a few times. That is because Corsair simply makes some of the best cases around, such as this one: The Crystal Series 460X.
The 460X is one beautiful ATX case to look at, as it sports a design that covers it in tempered glass, allowing you a view of the insides of your computer. Adding to the aesthetic of this case is the option of red or green LED lighting on the front of the case, making your computer emit a nice and soft glow.
For protection purposes, the 460X is fitted from head to toe with dust filters, keeping all the nasty dust and dirt out of your computer. You’ll want this protection as well, as you are able to fit many parts, including multiple GPU, inside this case snugly.
I have to say “snugly”, as although there are slots for stuff such as multiple GPU, the room inside this case is actually very limited in comparison to others. Not helping matters is a poor wire management system, which can leave wires hanging around loosely inside your build.
But this is a small price to pay for the Corsair Crystal Series 460X, as the beauty and safety of this case are just too much to pass up on, even if there could be a bit more space inside.
Corsair Carbide Clear 400CCheck The Corsair Carbide 400C’s Current Price On Amazon
As I had previously stated, Corsair is likely to pop up a few times on this list. This time, Corsair offers another case from their Carbide series, this time with the Clear 400C.
Thanks to an easy-access window panel located on the side of the case, it is easy to get into your computer and add or remove pieces as you please… maybe even a little too easy. While the ease of access to your computer is certainly great, the latch to open the window panel will open with the slightest of touches, which may expose the inside of your computer at an inopportune time.
Luckily, the protection you can get from this case makes up for that problem, as the steel frame and liquid cooling capabilities of the 400C will help to keep your computer’s parts safe from damage while keeping them chilled out. Two dust filters also help to keep your computer safe and are easy to remove and clean when you may need to.
If you decide to order one of these cases, make sure to double check the box it comes in, as there are sometimes parts missing that you will need. Things like zip-ties, screws, and manuals can all turn up missing from the box, making it a necessity to have to take a quick trip to a hardware store.
At the end of the day, you simply can’t beat this case’s convenience and safety measures. It is for those reasons that we think the Corsair Carbide 400C deserves to be called one of the best small ATX cases you can buy.
Lian-Li Case PC-A05FNBCheck The Lian-Li PC-A05FNB’s Current Price On Amazon
Lian-Li might not have the name recognition that some other products in this article may have. Don’t let this fool you, however, as the Lian-Li PC-A05FNB Case is likely one of the best small-form ATX cases you can find.
Adding parts to your computer is a cinch with the Lian-Li, as the panels on the case allow easy access thanks to their thumb-screw openings. Once you get the Lian-Li open, you will have plenty of space to work with as this case is designed to give you room to spare, despite its size.
The Lian-Li may not be liquid cooler compatible like some other cases, but it makes up for this by allowing you to use heat sinks to help disperse heat. You are going to need this too, as this case is compatible with SLI and Crossfire compatible hardware, allowing you to crank up the heat and overclock your games to your heart’s content.
There really isn’t anything bad that can be said about the Lian-Li PC-A05FNB, meaning this is a purchase that you can be proud of, no matter the cost.
Corsair Carbide Series 200RCheck The Corsair Carbide Series 200R’s Current Price On Amazon
Building a computer is an expensive endeavor as it is, with there being many different parts that you need to buy just to get your system running. Thankfully with the Corsair Carbide Series 200R, at least you can save a bit of money on your case.
With a price point just around the $60 dollar mark, the 200R is one of the most affordable small ATX cases you can buy. This helps to free up extra money to buy other parts you may need, such as fans and GPU.
What you save in money you pay for in space, however, as there is a bit less headroom for full-sized ATX MOBO to fit, making it a tight squeeze. And speaking of a tight squeeze, some of the slots for your various computer parts may hug your hardware snug, with many parts feeling like they actually have to bend to fit.
Even so, you do get a lot of value with your money, including advanced liquid cooling capabilities and seven slots for expansions. This case is also great for those that have a lot of external accessories, as there are several ports for external hardware.
While not the best ATX case you can find, the Corsair Carbide Series 200R has a lot to offer and is a great choice for those building on a budget.
Rosewill ATX Slim Full TowerCheck The Rosewill ATX Slim Full Tower’s Current Price On Amazon
Our next small-form ATX case comes courtesy of the folks at Rosewill with their Slim Full Tower. As the name suggests, this is one case that is as skinny as it gets.
While other small ATX cases are short and compact, the Slim is tall and thin. This design actually gives the case more room to fit larger motherboards and parts while still being small enough to fit comfortably into narrow nooks and crannies.
The case is also lighter than most, making it easy to move around if you need to. On the inside, you will find that you will have all the space that you could possible need and multiple expansion slots that can be used for your hard drives and fans.
Despite the extra space available to the user, the overall design of the Rosewill is very weak, with it being easier than it should be to break pieces off of the case. This issue can even happen before you open the box, with a lot of users claiming that they have received the product broken in the box and needed to get a quick replacement.
If you have a steady hand and think you can handle it, then you will get a lot of mileage out of the Rosewill Slim Tower. With a small size and plenty of room to expand, there are a lot of reasons to consider buying this ATX case.
Thermaltake Core G3 Slim Full ATX CaseCheck The Thermaltake Core G3 ATX’s Current Price On Amazon
There are few small ATX cases out there that can give you a wide range of potential building options. There are even fewer that can do so at a low price, which is the case with the Thermaltake Core G3.
While not the cheapest case on this list, the Core comes to an affordable price of around $70 dollars, making it one of the better options for building on a budget. For the price that you pay, you get a ton of extra options for making your perfect build that you can’t get with other cases.
This includes compatibility with multiple types of motherboards from both ATX and non-ATX products, which can all be easily installed thanks to an easy-access side panel. Providing, even more, potential building options is the fact that you can set up your case to either stand vertically or sit horizontally, enabling you to place your computer in the perfect spot.
There is a major issue with the Core as it concerns the PCI-E cable included with the case. This piece has a fairly high failure rate, with the cable either malfunctioning after a short period of time or failing to work altogether. As a result, you may have to contact the manufacturer for a replacement sooner rather than later.
There are definitely some faults with the Thermaltake Core G3, but all things considered, the positives far outweigh the negatives for this case. If you want a wide range of customization options at a low price, look no further than the Thermaltake Core G3.
RIOTORO CR1080 Full ATX Compact CaseCheck The RIOTORO CR1080’s FULL ATX’s Current Price On Amazon
On the surface, the RIOTORO CR1080 isn’t that much different than some other cases we have talked about, with it having a fan included and sporting multiple expansion ports like many others. However, there are certainly some things that help set this case apart from the competition.
For starters is the compartmentalized design of the RIOTORO. This design not only helps with cord management but helps to disperse heat and keep the computer cool even during high-strain.
The second thing that helps the RIOTORO step away from its competitors is its versatility. This case supports all types of ATX MOBO, from micro ATX to full-sized motherboards, making this a great choice for nearly every type of build.
While a larger motherboard is certainly capable of fitting in this case, the RIOTORO leaves little room for anything else. This makes it hard to fit both a full-sized MOBO as well as larger GPUs and other components in the same build.
The RIOTORO CR1080, with its support and technical capabilities, is one of the most versatile cases available today, giving you everything you need and more in one small package.
When you are lacking the space for your new computer build, then getting a case that is small but can fit all your parts is essential. Any of these nine options above are some the smallest full atx cases available, allowing you to build the perfect, compact computer of your dreams!
If you think we’re missing any cases from this list or if you need any additional help on finding the smallest atx case for you, please feel free to leave a comment below and I’ll make sure to answer as soon as I can.
