What Factors to Consider when buying the Smallest matx case?
Before you buy any Micro ATX case for your computer, there are a couple of features to keep in mind to save yourself from destruction… and get the best of the best as the market is already flooded with a variety of cases.
- Space for Components: If you have a small desk or several monitors, perhaps consider a simple option, then you can go for a small Micro ATX case. However, when you have enough space, then go for the large computer cases for the headroom for future updates. So before purchasing, you must make a list of all the products you want to install on your computer system — in this way, you can select the best one. The fan must be 80 mm to 120 mm in size so you can get the maximum performance.
- Air Flow: The airflow system is an essential part of the computer case. However, some of the cases have an unreliable airflow system that may cause heat-up issues. Remember to pick the Case with the best airflow and support more fans and radiators for the smooth working of gameplay. It is important to avoid the risk of overheating that may damage the other components of your computer. The Micro ATX Case must include two fans, at least from which one fan must be on the back of the housing to remove the heated air from the surroundings.
- Durability: When buying a Micro ATX case, the factor of durability is most important, so it must be kept in mind during the buying process. Quality should be your priority, don’t fall for traps by saving a couple of bucks. All aluminum and iron cases are excellent in durability. Therefore, the Case must be sturdy enough to prevent shock. The metal cases are best for use as they last longer as compared to others.
- Noise: Those PCs with dust filters, cooling options, and well management of cables reduce noise and work calmly. However, the airflow is more important for the proper working of the system. The use of more fans to make the system cool can cause more noise. In this situation, do not compromise with the cooling system and airflow to reduce the noise.
- Design and Customization: While purchasing a Micro ATX case, the first thing to consider is the Case’s design and how it is customized. The aesthetic designs of micro ATX cases are attractive, and everyone wishes to have the best one in hand. However, this is critical, and you have to know the details of the material before getting the good-looking Case. It is recommended that you must not buy a tempered glass case because it requires extra effort to hide the cables.
- RGB Lighting: The other attractive feature for gamers is the RGB lighting that allows them to customize the lights according to their mood. Therefore, you must go for the one that perfectly suits your personality.
- Cooling Option: Most of the cases have a weak airflow system that makes it have heating issues when the system is under pressure. Remember to choose the Case with the best airflow, and you can support the most fans and radiators for a smooth gaming experience. A case with better airflow makes your system cool even if it’s under pressure, hence, you get smooth performance no matter what.
- Budget: The price varies depending on the case and the brand. But it is always recommended to spend a bit more to get the best one in the market as you wouldn’t want something that is affordable but doesn’t last longer or has problems. However, the ones that we have listed above, don’t have this problem…
Features of Best Micro ATX Case
Micro ATX motherboards have gained popularity among gamers and professionals due to the following features.
- Arrangement of Cables: In one way or the other, the cable arrangement matters a lot — the mess makes your life messy, makes it necessary for one to do something about it later on… There could be short-circuited problems so the cables need to be easily manageable. In this regard, the Velcro and twist ties serve you in a better way.
- Removable Disk Filter: Micro ATX motherboards have a removable disk filter, which makes it easy to maintain. If you want to keep your computer clean and free of dust — a case with this option should be your target. Your computer case must remove the debris and dust efficiently and effectively without affecting the other components.
- Optional Drivers: Most of the micro ATX cases are not built to support all the optional drivers, and they cannot work properly in this regard.
- Drive Bays: Drive bays are the options for you to build and install your custom parts, such as temperature readouts, controllers, and hard drivers. Therefore, you must keep in mind that you are purchasing the right size components for your computer. The components’ size can be varied from 2.5 inches to 5.25 inches which are considered standard sizes.
- Motherboard tray: When purchasing a Micro ATX case for your computer, you must look for a motherboard tray’s details because it is the most critical part of the Case. The motherboard tray contains all the central components of your computer to provide quality performance.
- PSU Space: Since there are hundreds of PSUs out there, you need to ensure that the type of PSU you are getting for your gaming system is not vulnerable to voltage fluctuations. On top of that, Micro ATX cases only fit in specific dimensions. So, it’s always better to look for a PSU that fits your Micro ATX case well.
- Form Factor: Form factors have three types: full, mid, and mini-tower options that best suit ATX boards. In this way, you can decide about the size of the Case for your computer and the motherboard that can easily fit in it. In addition to these, there are several Tower Cases, SFF, and Small Form-factor cases available in the market.
- GPU Space: Your Micro ATX case must have a space that is enough to fix the graphic card in it because some graphic cards are large and require a lot of space. Therefore, you must choose a Micro ATX case that is a bit larger in size.
- CPU Cooler: The type of CPU cooler greatly affects the working of your computer. So, the Micro ATX case must have space for putting a CPU Cooler so that you can keep your computer cool and healthy. The quality of the cooling system can greatly affect your computer’s working efficiency and make it stable to perform well.
- PC Ports Case: Although the necessity of expansion arises from the motherboard, some cases offer different port expansions, for example, USB 3.1 Type C. These ports are just for enhanced compatibility, so it’s always better to look for the Case which offers such value-added features.
