Find out what parts you want
Before building a cool new computer all by yourself, you will want to know what motherboard, graphics card, and cooler you will be using. Also you will have to figure out how many drives you will want to install. This will tell you about the size and shape of the cases you should consider buying.
Full-towers, mid-towers and mini-towers are those form factors which usually support micro ATX boards. Unless you are building a powerful workstation, a mini tower will probably be the best PC case option for you instead of a full tower.
A cooler is an important part of your custom PC build. Therefore, always select a compatible cooler for your ATX case, because airflow is an important factor while choosing a micro ATX case. The better the airflow, the better is the thermal performance of your computer.
These are special slots inside a PC case for installation of fans for additional ventilation. Their sizes can vary from 80mm up to 200mm. Check the number of fans that you are going to need to build your computer. Then select an apt case that gives you enough space to fit in the fans without cramming the case.
Removable air filters
Look for removable air filters when you consider buying a chassis. Even though they are not present on every chassis, this promotes removal and reduction of excess dust inside the machine.
GPU clearance refers to the space required by a graphics processing unit to comfortably fit in the given space of a case. It means that there must be enough room inside your micro ATX case to house a chosen GPU. Do note that if a GPU clearance has 12 inches and more, then it will be able to support almost any video card.
Choose a case with cut-outs in the motherboard tray. This will let you route all the cables in the back of the case. This allows better cable management and convenient building of your computer.
Are micro ATX cases good for gaming?
Micro-ATX builds are extremely popular among gamers due to their efficiency, versatility, and affordable price point. Moreover, the best Micro-ATX cases provide the perfect chassis for both casual and hardcore gaming, with loads of great options to choose from.
Can a micro ATX fit in a ATX case?
Micro ATX motherboards can be used in full-size ATX cases. Micro ATX was designed to be backward compatible with ATX. The mounting points of micro ATX motherboards are identical to full-size ATX boards.
What is the difference between Micro-ATX and an ATX Case?
Micro-ATX is smaller than the regular ATX as the name suggests. ATX measures 305 mm x 244 mm, while the micro-ATX is more square-shaped, measuring 61mm x 244 mm.
Micro-ATX has lesser expansion ports compared to the full-sized ATX motherboard. Micro-ATX boards have three expansion ports, with four being the maximum, while ATX motherboards have five expansion slots.
Micro-ATX form factor has fewer drive bays than the full-sized ATX board. If you want more space to house any future expansions, a micro-ATX board is not a suitable option.
What is the difference between Micro-ATX and a mini ITX Case?
The first noticeable difference is the size of the two. The mini ITX is smaller that micro ATX. Micro ATX measures 244 x 244 MM and on the other hand, the mini ITX measures 170 x 170 MM.
The micro ATX supports up to 4 memory slots while the mini ITX version supports two slots. In case you want to expand your RAM mini ATX wouldn’t be a great option to choose.
The difference is more noticeable between micro ATX versus mini ITX when it comes to PCIe slots. The Micro ATX motherboards have four PCIe slots while the Mini ITX motherboard has 1 PCIe slot. Primarily, the slots are employed for integrating graphics card into your system.
Even though building your own computer rig can be expensive, you know it will have the components and the functionalities your computer needs to have. You can customize it to be a gaming computer or a workstation.
Micro ATX cases add to the functionality of a computer system. It helps in improved airflow as well as gives clearance to fit in all the desired components into your machine. You have to stick to a budget to buy a case and note down all the features you would be wanting out of the unit.
Follow your requirements and budget for choosing an advanced micro ATX case for your optimal system build.
