What Does ATX Mean, Anyway?
ATX means “Advanced Technology eXtended,” which is an unclear and unhelpful abbreviation. It’s a motherboard standard (also known as a “form factor”) that dates back to the mid-1990s and is still the most common type of board in consumers’ PCs today.
The ATX designation indicates the size and general architecture of the motherboard, which gives a rough indication of the number and kind of ports and expansion slots.
Some ATX boards, for example, may feature four RAM slots, while others may have six or eight.
Other Motherboard Sizes
Several (if not most) gaming PCs are equipped with ATX motherboards or a version of the ATX standard. There are well over a dozen of these varieties, but most are relatively uncommon.
The two most common smaller ones are Micro-ATX and Mini-ITX; despite its distinctive name, the latter is simply a version of the ATX standard.
Regular ATX boards are the largest and offer the extra expansion slots of the three varieties, allowing them to accommodate more (and consequently more powerful) hardware.
Micro-ATX boards are smaller and have fewer expansion slots than Mini-ITX boards, although both are more capable of powering a sleek and stylish gaming PC. A Mini-ATX form factor is smaller than a Mini-ITX board, although it is rare and poorly defined.
To buy one, you’ll need to study the characteristics of each specific board extensively; the “Mini-ATX” name is sometimes used so loosely that it’s possible to buy something other than what you were expecting.
Some form factors larger than ATX, such as EATX and XL ATX, will not fit in a small ATX case because they are too huge.
Also, while Micro-ATX and Mini-ITX boards will physically fit into an ATX chassis, the case may not have mounting holes, so double-check before purchasing.
Can an ATX Motherboard Fit in a Micro-ATX or Mini-ITX Case?
Numerous (but not all) ATX cases can handle smaller boards; however, if a case is promoted as a Micro-ATX or Mini-ITX case, it most likely cannot accommodate a giant board.
The critical word here is “readily”; if there’s enough space for the board, you can always make your mounting holes.
Read the product description carefully to see if the case is precisely what you’re looking for.
What Factors to Consider when buying the Smallest micro atx Case?
There are some things you should know before buying a Micro ATX case for your PC.
- Space for components – If you have a small table or multiple monitors, you might consider a simpler option. You can choose a Micro ATX small case. If you have sufficient space, consider purchasing large computer cases to allow for future upgrades. Before you buy, make a list of all the products you wish to install on your computer system. This will help you choose the right one. To get maximum performance, the fan should be between 80 and 120mm in size.
- Air Flow – The airflow system is an integral part of a computer case. Some cases may have an unstable airflow system, which can cause heat-up problems. For smooth gameplay, make sure you choose the case that has the most airflow. Overheating can cause damage to other components of your computer. Two fans must be included in the Micro ATX Case. At least one fan must be located on the housing’s back to remove heated air.
- Durability – When purchasing a Micro ATX Case, durability is the most important. This must be considered during the purchase process. Do not compromise quality for a few dollars. All iron and aluminum cases are durable. The case should be strong enough to withstand shock. Metal cases are the best as they last longer than other types.
- Noise – PCs with dust filters, cooling options, and well-managed cables reduce noise and operate more quietly. The airflow is crucial for the proper operation of the system. More fans can make the system noisier. Do not compromise on the cooling system or airflow in this instance.

Micro ATX cases have attractive designs, and every person wants the best. This is a critical step, so you need to be familiar with the case details before purchasing. Tempered glass cases are not recommended as it can be difficult to conceal cables.
- RGB Lighting – Another attractive feature for gamers is RGB lighting. This allows them to adjust the lights to suit their mood. You should choose the one that best suits you.
