Smallest ATX Case: Perfect For A Compact Gaming PC
by Stephen P
When building a new computer, the case is an important consideration.
You want to find one that’s big enough to hold all of your components but small enough to fit comfortably on your desk.
If you’re in the market for a new compact ATX case, you might be wondering if there are any small options available.
While most ATX cases are on the larger side, a few smaller models can still accommodate all of your components.
In this comprehensive guide, we’ll look at some of the best smallest ATX cases on the market. We’ll also discuss some of the pros and cons of these cases so that you can decide if they’re right for you.
The manufacturer has featured this PC case with high-end casing technology that you ever need for your ideal build.
It provides you with a lot of space for excellent cooling potential and lets you set your required components without traction.
A fast, clean, and more aesthetic setup is no more dream with this PC case because it gives you every possible solution for your casing complications according to your desired form factor.
Rather than typical fans, Corsair Carbide Air 540 comes with dual chambers with intake and exhaust fans to deliver more fresh air to inner components like CPU, motherboard, and graphics cards without restriction, which means it provides better airflow with low noise. It is no doubt a satisfying case for a clean and compact build.
Another incredible thing is its innovative cable routing system that lets you manage pumps and tubes in the liquid-cooling system.
It is built-in featured to support both cooling systems, so you can also select or switch your cooling system according to your requirements without compromising on aesthetics or replacements.
The PC case gives you tool-free storage and PCIe installation, quick and easy upgrading, and low maintenance requirements.
You can also quickly shift your ATX build to Micro-ATX or even to Mini-ITX. In short, the case gives you what you paid for and what you expect for your smart build.
NZXT is extremely successful in selling their PC cases; they give an attractive look that every gamer loves.
However, some users have reported that their cases are no good in terms of airflow. NZXT H510 CA-H510B-B1 is a compact mid-tower case that comes in three different color schemes. These color schemes match most of the latest motherboards, and you can select them according to your choice.
This case gives aesthetics and excellent thermal and acoustic and one of the company’s most famous lineups.
NZXT H510 has seven expansion slots and supports a ATX motherboard with a better cable management system than other cases.
This case’s body is made up of steel and tempered glass on the right side and has matte black color throughout the case.
For cooling, it supports four fans, from which two are on the front panel and intakes air, one on top and one on the rear side.
You will also get two Aer F120mm fans in the box installed on the front panel. If you are super crazy about overclocking and temperatures, you can add water cooling systems and custom loops.
As I said, earlier NZXT cases are built so that they limit the airflow in the case. Having metal front and glass on the side might restrict airflow in case, but if you want to get the best airflow, I would recommend you to use static pressure fans on the front panel. If you mount a 140mm fan on the top side, it might block the eight-pin connector on the Motherboard.
Also, the GPU holding screws setup is outdated in this case.
If you prefer aesthetics and RGB, this case is made for you, but the airflow is not the best in its class.
This case hurts with the metal front panel, and it will be more than enough if it is made up of mesh.
There we have another Cooler Master case for you which looks gorgeous and is the best in its class. Cooler Master MasterCase SL600M is built with high-quality aluminum and has all the premium feature an enthusiast PC demands.
This case’s color scheme is silver, and the interior is colored black, which gives it an attractive look.
The airflow system of this case is high enough, and it can efficiently cool down high-end CPUs.
Also, with that cooling, you are not going to listen to the noise of fans even under full load because they are set up in such a way to make noise at the minimum level.
MasterCase SL600M supports every type of motherboard, including mini-ITX to extended ATX, having nine expansion slots.
This motherboard doesn’t have fans mounting space on the front or rear panel; instead, it has top and bottom. On the top side, you can install up to two 140mm fans and one 200mm fan, and on the bottom, there is mounting space for two 200mm fans. This fan arrangement gives the best airflow within the case and cool down all your components. You can install two 3.5 inches hard drives and up to eight 2.5 inches hard drives on it.
There is enough space for graphics cards, and you can also use any big size CPU cooler, up to 191mm in max cpu cooler height, with this chassis.
This chassis is best for you if you don’t like noisy fans or your PC mostly runs on high load. It comes with a modular I/O design having one USB 3.1 Type-C port and several high-speed USB ports on the front panel. It also has a proximity sensor that lightens up the USB ports so that you can install USB cables in the dark, but it’s too sensitive.
This casing’s rear side looks quite different from other chassis, and it lacks PSU remote switch and rear fan mounting space. It has seven expansion slots, which are placed horizontally, and two are placed vertically.
Overall, it’s the right choice for small form factor computers, but it’s not the right choice for LAN gamers.
You can use it for home, gaming, and office builds, but there are some other choices if you are looking for something bling.
I would recommend you consider this if you want a subtle look and can afford its premium price.
Like a smart manufacturer, this brand better knows users’ needs and requirements. One of its powerful products, named Cooler Master MasterBox Q500L, is fully capable of meeting your micro-ATX build requirements. Micro-ATX has become an ideal set up these days because you need a massive system in general cases.
Smart users like to build a standard rig that takes a reasonable space on their table.
As quality and performance are not measured by size, a micro-ATX has become a favorite choice.
This console-like case is perfect for those who want to minimize the size of their build without sacrificing performance or features.
The fully perforated chassis offers airflow for various fan configurations, and the movable I/O panel means you can choose how you want to set up your case.
The vertically and horizontally reversible design means you can set it up however you want, while the rubberized screws keep your equipment in place.
Plus, with the PSU mounted on the front of the chassis, you’ll have more room to work inside.
Featuring a body depth and height of only 386 x 381 millimeters, the MasterBox Q500L is a great option for anyone looking for a high-quality, reliable case for their next PC build.
Corsair is a top-notch Gaming peripherals brand, and the reason behind their success is top quality products and affordable prices.
Crystal Series 460X RGB comes with two-panel tempered glass and three RGB SP120 fans mounted on the front panel.
You might be thinking, what does this SP mean? Corsair fans come in two models specializing in Airflow AKA AF, and the other one is Static Pressure or SP, and both are quiet and best in performance.
This casing comes in black color and is made up of steel and tempered glass. This case is engineered well and packs all of your components in the best way to give airflow and aesthetics both.
CORSAIR Crystal 460X RGB comes with seven expansion slots and supports ATX, micro-ATX, and mini-ITX motherboards with multiple graphics card setup.
As I mentioned earlier, it comes with three pre-installed fans on the front panel, one 120mm fans space on the rear side, and two 140mm fans mounting areas on the top side.
This casing is designed in such a way to give maximum cooling to all the components inside it.
There is mounting space for two 3.5 inches hard drives and three 2.5 inches SSDs or laptop-grade HDDs. You can install a CPU cooler with a maximum cpu cooler height of 170mm and a graphics card of length 370mm.
This casing’s main plus point is two-sided tempered glass and pre-installed RGB fans; however, the RGB controller lacks turn off the function.
There is limited space for cable management because of its small size.
It supports three 120mm fans for the front, but you can’t install three fans 120mm radiators on it; also, it doesn’t keep long power supplies.
The number of bay drives is not enough for enthusiast builds but acceptable.
Overall if you are looking for great aesthetics and cooling solution, this case is made for you. Its price is not high, just like other Corsair products, and gives features found in premium cases.
However, you can’t carry this casing as it is not built for that purpose.
Thermaltake is another reputed brand providing the best value products for several years. Their products are well known for style points and usability. Thermaltake Core G3 ATX is a slim tower case and can be used for any small form factor build.
This case’s interior and exterior are colored in black, and it is made up of steel.
If you haven’t used slim cases before, you might find it strange because its front and rear side doesn’t look the same as mid-tower cases we usually use.
The Core G3 comes with two 120mm Turbo fans installed on the front panel.
Inside the case, there are two slots for bay drives; it’s up to you either you install two 3.5 inches drives or two 2.5 inches drives.
There are two expansion slots on the back of the chassis, and you can install any dual-slot graphics card, but you can’t use multiple graphics cards or PCIe x1 slots. As it is a slim size case, you can’t install big size coolers and PSUs on it, or they will conflict with the right panel.
There is mounting room for the fan on the top of the case, and you can install a 120mm fan, which blows air on the graphics card.
Core G3 supports ATX, micro-ATX, and all other motherboards; however, your GPU length must be placed vertically using e-raiser cables.
You can install multiple fans on the front panel, and if you are planning to use a liquid cooler, you can also use a 240mm radiator.
This case is right for LAN gamers because it’s lightweight and easy to carry.
Cable management, in this case, is not that good, but it’s totally up to you how you manage it.
Overall, this casing is best for slim or SFF builds and weighs approx. 9.3 lb makes it best for LAN gamers and is the cheapest case on this list.
If you are looking for something that gives aesthetics and excellent cooling, you might better go with NZXT H510.
