Before Shopping for PC Cases
Before shopping for PC cases, consider a few key factors to make sure you find the perfect case size for your needs.
Here’s what you should keep in mind:
- Determine Your Budget: PC cases range from budget-friendly options under $50 to premium models over $500. Setting a budget up front will help narrow your choices and prevent overspending.
- Consider Your Motherboard Size: Make sure the case you choose is compatible with your motherboard form factor, whether ATX, Micro-ATX, or Mini-ITX. Verify this before buying any other components.
- Think About Your Cooling Needs: Do you plan to overclock your CPU or install a GPU that generates enough heat to feel like a small space heater? If this is you, you’ll need a case with excellent airflow and cooling options. Not all PC cases offer the same airflow capabilities, so look for cases with multiple fan mounts, mesh panels, and room for liquid cooling.
- Check the Case’s Features: Features like cable management, drive bays, and front-panel ports can make a big difference in your build experience. Look for cases with built-in cable routing channels, plenty of drive bays, and easy access.
Of course, with features comes cost. You’ll find many computer cases that fit your budget by considering the features you need.
PC Case Form Factors: Which Should I Use?
First, let’s get familiar with PC case sizes and the motherboard form factors they support. This choice is basically about whether your motherboard will fit.
The form factor of a PC case refers to its size and shape, which can affect which motherboard and other components will fit.
Here are some common PC case form factors:
-
Full Tower: Full tower PC cases are the giants of the PC world, often exceeding 20 inches in height. These cases can accommodate large E-ATX motherboards and custom loop cooling systems, making them ideal for high-end enthusiast builds. A full tower is your best bet if you plan to go all out with multiple GPUs and extensive cooling.
-
Mid-Tower: Mid-tower PC cases strike a balance between size and functionality. Typically around 20 inches tall, they offer plenty of space for most ATX and even some E-ATX motherboards. Mid-tower cases are perfect for anyone who wants a versatile build without the bulk of a full tower. They provide enough room for a robust cooling setup and multiple storage options, making them popular with gamers.
-
Mini Tower (MicroATX): This compact case size is ideal for minimalist builds. You need to be more selective with your component choices, but they save desk space. These cases are designed to fit micro-ATX motherboards, balancing size and functionality.
- Mini-ITX: Mini-ITX PC cases are designed for mini-ITX motherboards and small-form-factor PCs. These compact cases are ideal for portable and unobtrusive builds. However, mini-ITX cases can be thermally challenging, especially with high-end components. If you’re looking for a sleek, minimalist setup, be prepared to carefully manage your cooling and component choices.
Some specialty form-factor cases are also designed to accommodate larger-than-normal E-ATX motherboards. These cases are typically used in enthusiast-grade custom builds, where multiple GPUs and custom water-cooling loops are common.
Tip: By choosing a smaller case, there will be limitations on the PC components that will fit.
PC Case Size and Dimensions
Size matters—in more ways than one. The case dimensions determine what you can cram inside.
- Airflow Considerations: Bigger cases usually mean better airflow, which helps keep things cool. Not all PC cases offer the same airflow capabilities, so smaller cases can be more restrictive, leading to overheating.
- Component Compatibility: Always check if your motherboard, GPU, and other components will fit. There’s nothing worse than realizing your shiny new graphics card is too long. A mid-tower case is popular for its balance of size and capacity, accommodating various motherboard types, including ATX and Micro-ATX.
- Usage Guidelines: If you’re a gamer or run demanding applications, use a larger case with good cooling options. For basic tasks, a smaller case might be enough. Small-form-factor cases are an option for those looking to save desk space, though they limit the components they can support.
Tip: Consider picking the largest PC case that fits within your budget and space.
PC Airflow
Ever use a laptop with it sitting on your lap, and then it gradually gets too hot to keep there? That’s bad airflow. For desktop PCs, good airflow is essential for several reasons.
- PC Performance: Good airflow keeps your components cool, boosting performance and lifespan. Overheating can cause throttling and crashes, especially on a high-end gaming PC.
- Design Features: Look for cases with mesh panels, multiple fan mounts, and space for liquid-cooling setups. Not all PC cases offer the same airflow capabilities, so these features help circulate air efficiently.
- Restrictions: Avoid cases with solid front panels or glass panels with limited airflow. They might look cool, but they can trap heat.
- CPU and GPU Cooling: These are your hottest components. Make sure your case has enough fans to keep your PC cool during those gaming sessions. Also, choosing a case with room for a large CPU cooler is important to achieve the best cooling performance.
Tip: You’ll find many good videos online that discuss fan setup for effective PC cooling.
PC Cooling Solutions
Cooling is a key consideration in PC building, and the right cooling solution can make a big difference in performance and noise levels. Here are some standard cooling solutions:
- Air Cooling: Air cooling is the most common cooling solution, using fans to circulate air through the case and cool components. It’s straightforward, cost-effective, and easy to install. Most PC cases come with pre-installed fans. Just make sure your case has enough fan mounts and a good airflow design to keep things cool.
- Liquid Cooling: Liquid cooling uses a coolant to absorb heat from components and transfer it to a radiator for dissipation. Liquid cooling can be more effective than air cooling, especially for overclocked CPUs and GPUs, but it requires a more complex setup and maintenance. If you’re up for the challenge, liquid cooling can offer superior cooling performance and a quieter system.
- All-in-One (AIO) Coolers: AIO coolers are liquid cooling solutions that combine a radiator, fan, and pump into a single unit. They are easy to install and require minimal maintenance, making them a popular choice for those who want the benefits of liquid cooling without the hassle. AIO coolers come in various sizes, so make sure your case has enough space to accommodate the radiator.
Choosing the right cooling solution depends on your performance needs, budget, and willingness to manage maintenance. Whether you go for air cooling, liquid cooling, or an AIO cooler, make sure your case supports your choice so your system runs smoothly.
Drive Bays and Storage
When choosing a PC case, drive bays and storage options are also important considerations. Here are some things to keep in mind:
- Drive Bay Types: If you still use traditional SSDs and HDDs, look for cases with 2.5-inch and 3.5-inch drive bays to accommodate both. This flexibility allows you to use both SSDs and mechanical hard drives.
- Storage Capacity: Consider the number of drive bays and the overall storage capacity you need for your build. If you plan to use multiple drives, make sure the case has enough bays to support them. This capacity is important if you’re building a DIY NAS unit.
- SSD Mounting Points: Look for cases with dedicated SSD mounting points or caddies for easy installation. These mounting points often simplify cable management and improve airflow within the case.
While drive bays are less important with the latest NVMe storage options, they are still handy for installing a few older mechanical HDDs as affordable secondary bulk storage. Especially with today’s prices!
Will Your PC Parts Fit?
An oversized GPU won’t fit into a compact case. Don’t try to play Tetris with your PC parts.
- Fitting Parts: Double-check the specs of your case and components. Length, width, and height all matter. Most will show what fits where. A computer case that can fit all your components, including the GPU and CPU cooler, is important.
- Common Fitment Issues: Graphics Cards (GPUs) and CPU coolers are the usual culprits. Some high-end models are enormous and won’t fit in smaller, shallow PC cases.
- Measurement Tips: Just like cutting wood, measure twice, buy once. Use a ruler and compare the size of your parts with the case’s internal dimensions.
Tip: Choose a PC case before buying any other parts.
PC Cable Management
Just shoving cables in wherever they fit will ruin an otherwise great build. Clean cable management isn’t just about looks. It’s about clean airflow, and choosing the right power supply matters.
- Why It’s Important: It improves airflow and makes your PC easier to work on. Plus, it helps avoid accidental disconnections.
- Helpful Features: Look for cases with built-in cable routing channels, tie-down points, and plenty of grommets. These make keeping things tidy a breeze.
- Extra Cable Ties: Consider buying extra cable ties to make things neat and tidy. Even if you’re the only one who will see it.
Tip: Use a modular power supply so you only need to use the cables required.
PC Design
The PC case is a part of your personal style and a major part of your overall workspace design. Try to choose a PC case that fits both.
- Personal Preference: Your case should reflect your style. You could go full-on with RGB lighting and water cooling or choose a minimalist design. Either way, your PC design should be something unique to you.
- Picking the Right Design: Think about where your PC will sit. If it’s under a desk, a simpler design might do. Or, if it’s on display, load that baby up with RGB lighting.
- Custom Builds: For themed builds, pick a case that matches your color scheme and is easy to modify. Make it your own!
Tip: If you make any modifications, make sure that airflow isn’t restricted.
Connectivity and Front-Panel Ports
PC Case connectivity and front-panel port placement matter for ease of access.
Here are some things to consider:
- USB Ports: Look for cases with multiple USB ports, including USB-A, USB-C, and USB 3.2 Gen 2. These ports provide easy connectivity for peripherals, external drives, and other devices.
- Audio Ports: Consider cases with front-mounted audio ports. These ports make it easy to plug in headphones for some privacy while you’re gaming, watching movies, or listening to music.
- Front-Panel Control and Indicators: Look for cases with convenient front-panel controls and indicators, including power and reset buttons and LED indicators. These features make it easy to power up and monitor system status, including storage drive activity.
Most PC cases include these basics. However, some offer more than others, including SD Card readers and removable storage bays. You need to decide which is most important to you.
PC Style and RGB Lighting
Style and RGB lighting can enhance the visuals of your PC build. Here are some things to consider:
- Tempered Glass Side Panel: Look for cases with tempered glass side panels for a premium, visual look. These panels let you show off your internal PC-building skills, especially if you build a custom water-cooling loop.
- RGB Lighting: Consider cases with built-in RGB features. RGB lighting lets you customize your PC’s look to blend it into your personal space.
- Color Schemes: Choose a case that matches your color scheme and decor. Some folks prefer a minimalist design, a bold and colorful look, or something unique or theme-based. Start with the right case and make it your own.
RGB lighting lets you create a PC build unique to your style. And, if you’re not sure where to start, search online for some inspiration.
Additional Case Features
Some extra bells and whistles can make your life easier. Look for these often-overlooked features.
- Swappable Drive Bays: These are absolute game-changers! Swappable drive bays let you easily add or remove hard drives and SSDs without the hassle of searching for a screwdriver. This convenient option makes upgrading your storage or swapping drives a breeze.
- Removable Dust Filters: These filters are easy to clean, simplifying maintenance. They trap dust before it settles, helping maintain optimal airflow and preventing overheating, so your PC runs at its best.
- Tempered glass panels: Many users prefer their sleek, modern appearance, highlighting internal components, especially those with RGB lighting. They are more durable than acrylic, resisting scratches and impacts, making for a long-lasting, scratch-free look.

So, what kind of PC are you planning to build? We’d love to hear from you. Leave us a comment below.
Questions I’m Often Asked About PC Building
How do I know if my GPU will actually fit in a specific case?
You need to check two specific measurements: GPU Length and Slot Width. Every PC case has a “Maximum GPU Length” specification (usually in millimeters). Compare this to the length of the specific GPU model you are buying. Additionally, make sure the case has enough expansion slots on the back if you are using a thick “3-slot” or “4-slot” high-end card.
Is a “Mesh” front panel really that much better than “Tempered Glass”?
Yes, in terms of thermal performance. A Mesh front panel allows fans to draw in fresh air directly from the room with minimal resistance. A Tempered Glass front panel looks nice, but often forces fans to breathe through small side vents, which can increase component temperatures by 5°C to 10°C or more. If you have high-end, heat-generating parts, mesh is the safer bet.
Can I put a small motherboard (Micro-ATX or Mini-ITX) into a large Full-Tower case?
Technically, yes. Most Mid-Tower and Full-Tower cases have mounting holes for smaller motherboard standards. However, it may look “empty” inside, and some cables (like the front-panel headers) might have a long reach on a smaller board. Most builders prefer to match the motherboard size to the case size for a cleaner look.
What is the difference between a “Modular” and “Non-Modular” PSU for cable management?
A Non-Modular power supply has all its cables permanently attached, meaning you have to hide the ones you don’t use (which is difficult in small cases). A Modular power supply allows you to plug in only the cables you need. This significantly reduces clutter, improves airflow, and makes the building process much less frustrating.
Do I need to buy extra fans, or are the ones included with the case enough?
It depends on your hardware. Budget cases often come with only one “exhaust” fan, which isn’t enough for a gaming PC. For a balanced setup, you generally want at least two intake fans (front) and one exhaust fan (rear). If you’ve chosen a case with only one fan, you should buy two extra 120mm or 140mm fans to make sure you achieve proper cooling.
I learned the hard way about GPU clearance! Always double-check the specs of both your card and the case!
Exactly! Measure twice and then again, just for good measure! 🙂 Today’s GPUs are massive! I also consider leaving enough space in the case for a future GPU upgrade, although I can’t imagine how much larger they could get.
I went for a really flashy glass case and while it looks cool, the airflow isn’t great and my AIO stuggles to keep my CPU cool. Any suggestions on fan layout? I’ll definitely prioritize function over form next time.
Every case will be different and fan placement makes a big difference in airflow. If you’re using an AIO, as you said, airflow over the CPU is less important.
Additionally, if you’re using a high-end GPU that generates significant heat under load, consider a bottom-to-top fan configuration. If your case supports bottom-mount fans, draw air in from the bottom and out the top, as heat naturally rises.
There are numerous informative videos on YouTube that experiment with various fan placement options.
I’ve been on the fence about what case to buy for my first PC build. This was helpful, especially about makign sure it all fits! I’m thinking about a mid tower and hadn’t really given that much thought. Until now! 🙂
Most cases will list what motherboard sizes they support as an obvious spec. Some less obvious are AIO radiators and tower cooler clearences. I once assumed a tower cooler would fit, but not only was my RAM too tall, the case was too narrow to allow me to put on the side panel. Needless to say, I returned it for another option that fit! 🙂
Nice detailed guide! Regarding case airflow, do you have any recommendations for cases that balance good airflow with quieter operation?
The choices are endless. I’ve built several systems using all sorts of case designs. Those with the standard three front fans and a glass side panel, and the “fish tank” style with a glass front and side that uses a bottom-to-top fan configuration for a chimney-like airflow design.
However, my last build was in the new “Corsair Frame 4000D“. This case has the best air flow of any other case I’ve used and keeps everything much cooler than I expected. However, with the case being more open and mesh, the fan noise is more noticeable, but that seems to be the trade-off vs cases wrapped in glass.
