How to Choose a Computer Case


A computer case is a component important for your system. It protects all of your components and plays a big role in influencing airflow to keep them running cool. But with so many case options with different sizes and designs, the fact is, when choosing a computer case there is a lot to consider. This article will go over four different factors (some with a lot of sub-topics) to consider when choosing a case for your PC build. Hopefully, by the end of this post, you’ll have a better idea of what to look for in a case so that you can be better able to find the best PC case for you and your new system.

Part 1
Determine The Form-Factor

The bigger the case, the more variety of motherboards can be placed. The commonly available types of cases are Full Tower (Large), Mid Tower (Medium), Micro-ATX (Small), Mini-ITX (Smaller). Smaller form-factor cases are rarely used. They are limited by their size but they are mostly chosen for smaller spaces and ease of transport.

Check whether your graphics card fits properly, with enough room for airflow. Get a small form-factor case with a “mini” graphics card if you want to occupy less space. Consider your air CPU cooler height, or, whether your liquid cooler with radiator will fit inside.

Think Good Cooling And Air Flow

Some cases come with fans pre-installed, these are great options as you don't need to purchase them separately. Configure your fans for positive air pressure to keep dust from being sucked in.

They are an ideal option because they limit the dust flow into the case. Choose a case with large open and grilled panels for good airflow, which keeps your components cooler. Cases that have solid panels restrict the air coming in and exiting the case.

Prioritize Cable Management

Look for features like: Plenty of holes and hooks/loops all over the case. Rubber grommets around the holes to conceal the gaps. Cases with good depth behind the motherboard to accommodate large cables. Shrouds for non-modular PSUs.

USB-A Type 2.0, USB-A Type 3, USB-C, and even fan or RGB lighting controllers will satisfy all your needs. You’ll often find front-panel audio jacks as well, though it's better to use the audio jack on your motherboard’s rear I/O shield.

Part 5
Pay Attention To Sound

When you use your system at full load, the fans spin at high speed, which creates a loud sound. To counter this, you can go with an AIO cooler (water cooler).

Some higher-end cases come with soundproof cabinets, which don't impede airflow.

Think About Build Quality And Case Aesthetics

1
A budget-oriented case is completely fine. But be aware of lower-quality materials. Buying a computer case is purely on your choice, liking, and taste. If case aesthetics are important, you can buy a case with see-through side panels. Avoid an acrylic see-through side panel as they get scratched easily. Tempered glass side panels are your best bet. Look for customizable RGB lighting.

These come between $20 to $90. They are affordable, easy-to-carry, and have plenty of ventilation for improved airflow. Some of them come with a full-sized power supply. Mid Range cases come between $95 to $150. These are comparatively affordable and made for good visuals. They have plenty of ventilation for improved airflow. Some of them come with a full-sized power supply. Some include integrated RGB lights, vertical GPU mounts, and software to control your LEDs and optimize your fan speeds. High-end cases come between $165 to $250. These are completely made for good visuals with best sound-proofing, great airflow, plenty of room for multiple graphics cards and room for complete AIO or custom water coolers.
