Are you building a new computer or upgrading an existing one? The computer case is one of the most essential components you'll need to consider. In this article, we'll go over some tips to help you in choosing the perfect case for your computer.

When it comes to finding the perfect computer case, you have to remember that not only does it protect your components, but it also affects your computer's cooling and noise levels. With so many options on the market, choosing the right computer case can be overwhelming.

Size matters: The first thing you will need to consider is the motherboard that you are going to use. The most common sizes are ATX, Micro-ATX, and Mini-ITX. Make sure you choose a case that fits your motherboard size.

Beyond that, you'll also need to consider the size of your graphics card(s), power supply, CPU cooler (air or liquid), and drives you plan to install.

Airflow and cooling: Proper airflow is crucial for keeping your components cool and extending their lifespan. Look for a case that has plenty of ventilation and supports multiple fans. You may also want to consider a case with liquid cooling support if you plan on overclocking your CPU (Central Processing Unit) and/or GPU (Graphics Processing Unit). Remember, a larger case will give you more room for expansion, but it will also take up more space on or below your desk.

If you plan on using a liquid cooler for your CPU and/or GPU, you will need to take into consideration the size of the radiator(s) and cooling fans. The mounting depth for a cooling radiator with fans attached can vary, so definitely make sure you have plenty of clearance in the case where you plan on mounting the cooling system. Remember that a case with more fans will generally be louder than one with fewer fans, so you'll need to find a balance between cooling and noise levels.

Noise levels: Speaking of noise levels, consider the noise output of your case. If you're building a home theater PC or a workstation that needs to be quiet, look for a case with sound-dampening materials and low noise output. On the other hand, if you're building a gaming PC that will be under your desk, noise may not be as much of a concern.

Cable management: A clean and organized interior not only looks better but also helps with airflow and cooling. It also comes in handy when it comes to maintenance. Look for a case with plenty of cable management options, such as routing holes and tie-down points. Some cases even have built-in cable channels to help keep everything tidy.

Build quality: Next, consider the build quality of the case. You want a sturdy, well-made case with no sharp edges or flimsy panels. A good case will also have easy-to-remove panels to access your components easily.

Some 'no name' generic cases have a tendency to have metal edges that are not deburred, leaving them extremely sharp, which will lead to cuts on your hands as you assemble your computer. Since a good quality case can last for years, spending a little more on a quality case is just good sense.

Serviceability: With living in a dry environment like Phoenix, we have an extreme amount of dust and need to clean our systems on a regular basis. Having a computer case that can be easily cleaned of dust is essential.

Remember that most computer cases also come with dust filters that need to be cleaned, so having side and top panels that can be easily removed is handy.

In addition to these tips, you'll also want to consider the overall style and design of the case. Do you want a sleek and minimalist look or something with more RGB lighting and flashy designs? Ultimately, the right case for you will depend on your personal preferences and needs.

Common problems to avoid when building your own computer

Are you planning to build your own computer? It can be an exciting project, as you get to choose the components that match your needs and preferences. However, building a computer from scratch can also come with its own set of challenges and errors. In this article, we will discuss the common problems to avoid when building your own computer.

Having built and serviced many custom-built computers, there are certain things I watch out for. The tips outlined in this article are meant to assist you in building your own computer. For the basic steps to building a custom computer, check out How to build a computer.

Choosing components: One of the most common mistakes people make when building their own computer is selecting the wrong components. You must choose components that are compatible with one another. For example, if you choose a motherboard that only supports DDR4 RAM, you won't be able to use DDR5 RAM, no matter how much you want to.

Enough space for components: When building a computer, it's essential to make sure that you have enough space for all the components. If you're building a Small Form Factor computer, make sure that all the components you choose can fit inside the case. It's also essential to make sure that there is enough space for adequate cooling and airflow. Remember, you cannot install a full-size ATX motherboard into a microATX case.

Things to keep in mind when building a custom-built computer

Motherboard IO shield: If your motherboard comes with a separate IO shield, remember you have to install it before the motherboard. Also, be careful when installing the motherboard so you do not bend any of the prongs on the IO shield.

These prongs are meant to ground the various ports but often get bent out of shape. Install the IO shield in the case and then test fit the motherboard into the case. If you place the motherboard at an angle in the case, you can get the ports on the back underneath any IO shield prongs that need to be on top of them.

Cable Management: Cable management is often overlooked, but it's essential to keep your computer tidy and organized. Proper cable management can help with airflow, reduce dust buildup, and make it easier to troubleshoot any problems. Make sure that all cables are neatly tucked away and secured to avoid any damage or interference with other components.

When performing cable management, use only velcro or plastic zip ties. Never use plastic-coated wire twist ties since they contain wire, which, if used too close to any exposed circuit board or bare metal, could cause a short.

Power Supply Requirements: The power supply is one of the most critical components of a computer, and it's essential to make sure you get the right one. A power supply that isn't powerful enough can cause your computer to crash, and one that is too powerful can waste energy and increase your electricity bill. Make sure that your power supply can handle the wattage required by your components.

Also, use a modular power supply if possible. With a modular power supply, you only have to attach the cables required for the components inside your case. For example, if you use only M.2 SSDs (Solid State Drive) for storage, you would not need to attach any SATA cables to the power supply, thus saving space inside the case.

Cooling: The components inside your computer generate a lot of heat, and it's essential to keep them cool. If your computer overheats, it can cause damage to the components, shorten their lifespan, and even cause them to fail. Make sure you have enough cooling, either through fans or liquid cooling, to keep your computer running at optimal temperatures.

When it comes to the airflow direction, I usually will have air coming in through the front/bottom of the case and going out through the top/back of the case.

Case fans typically are marked with the direction of both the fan blades and airflow.

In conclusion, building your own computer can be a fun and rewarding experience, but it's essential to avoid these common problems. Take your time, do your research, and make sure that you choose the right components that are compatible with one another. Always double-check that everything is installed correctly and that you have enough cooling and space for all the components. With the right approach, you can build a computer that meets your needs and performs well for years to come.
