Factors You Should Know Before Buying a Quiet PC Case

Cooling & Thermal Performance

A good PC case always keeps the components cool. To do that, these can either use the pre-installed fans or you can install better fans after-market.

These fans create a nice airflow that ventilates the case to keep the components cool.

There’s also liquid cooling which is a bit more expensive but works better with higher-end builds. And guess what? It’s also much quieter than the fans.

Nonetheless, many buyers look for a pre-installed solution for the fans.

In such a case, the Fractal Design Define 7 with its 9 pre-installed fans is a no-brainer for anyone who wants a decent thermal performance without any new additions.

Form Factor

Motherboards come in several different sizes and specifications. That’s why there are different form factors for PC cases to suit all of those motherboards.

A general rule of thumb is to always check the compatible motherboards before buying a PC case.

You also need a decent-sized PC case with good GPU clearance to fit the most powerful GPUs.

It’s always important to note that a larger case won’t be a problem for smaller motherboards.

In fact, a slightly larger chassis may also be a better solution for good airflow throughout the case as it makes the installation process a little easier for novice builders.

In case you aim for a mini ITX motherboard, a case like the Fractal Design Define Nano S would be best.

Pricing & Additional Costs

Great quiet PC cases exist but everything begins with budget.

Whenever you buy, analyze the case to find the ideal price point and other additional costs involved.

Don’t pay just for the sake of brand or it looks cool, make sure you check out the performance well enough.

And if I see it from a budget view-point, the Corsair 100R would be a great choice to minimize any additional costs for budget builders or first-time PC owners.

Materials & Build Quality

Before building a PC, most buyers look for a long-term solution. Having a durable PC case will add to that and stay with you for years to come.

Even after you plan to upgrade the PC specs or the motherboard, there is a good chance that you may not need to change your PC case at all.

Stronger materials also give a premium touch to the case that feels and looks fantastic.

On the other hand, low-quality materials can cause the panels to flex and can cause damage to the hardware inside the case.

After-Market Add-Ons

Some of the cases we listed have almost everything pre-installed. However, some may not have what you need.

For instance, there may be additional slots for more fans to be installed for better airflow.

You need to decide what things need to be added to the PC case to make it a more complete design.

Cable Management

Keeping the PC clean and tidy is crucial. After all, the maintenance aspect of having a PC may not come to you at first but will trouble you in the long run.

Having a nice cable management solution will keep the internal components organized and remove the cable obstructions for the airflow.

The Bottom Line

Among these, Fractal Design Define 7 is best from all aspects.

Although the Cooler Master Masterclass SL600M is a better alternative, the price factor really makes the Define 7 stand out.

If budget is not a concern, you can make a safe decision to go with the SL600M as it has all kinds of cool features and effective cooling method!
