Features To Consider – Buyer’s Guide
Whenever you are hunting for the best case available, there are a few things you must keep in mind before you make a choice. The following features are vital to consider as they’ll significantly impact your PC performance.
If you have already bought other PC components before purchasing a case, you must find a suitable case that perfectly fits all your components. Make sure the size of your motherboard, PSU, CPU coolers, and other hardware is compatible with your case before you proceed to buy on.
Build quality is of great importance when buying a PC case. If your PC lacks good build quality, you’ll soon see scratches and dents all over your setup, with pain removing from most spaces. This will render your PC out of shape and make it look so much less attractive.
On the other hand, a sturdy case will speak for itself. Aluminum and steel are mainly used on PCs with excellent build quality, improving the overall impression of your setup.
When buying a case, you must find out which motherboard form factors the case supports. Some of the most popular form factors are ATX, Micro-ATX, Extended ATX, and Mini-ITX. If your case isn’t compatible with the motherboard you desire, you must look for another case that does fit in your motherboard.
It’s a blessing to have decent cable management in your case. This keeps everything organized, preventing all the cables from getting tangled up. Other than that, your PC will look super neat, and you can easily manage the cables while making adjustments. So, cable management is something essential to consider.
Airflow and Filtering
Lots of cases have weak built-in airflow systems. If you are buying a case, it must have at least two built-in fans, along with options to add more. This will improve your ventilation system and keep things from getting heated. Moreover, the cooling system you can install also depends on the compatibility with the case.
Dust filters are essential, and all the best cases should have them. These filters remove dust particles, providing a clean and efficient environment for your components to work optimally.
Drawbacks Of Tiny PC’s
Although compact PCs have many advantages, there are a set of drawbacks to consider if you’re going for a small ATX case.
If you’re going to stuff all the high-end hardware for gaming/content creation or other uses in a tiny case, airflow will be a problem. As the compact cases are only half the size of a typical case, a hindrance to airflow will be caused, and keeping all the components cool will be a difficult task. However, some cases come with great cooling features that discard this problem.
A smaller case means you won’t be able to load your PC with all the best hardware as there isn’t enough room in there. This means there are fewer options for upgrading, and you can only install the hardware that fits in. You will also be using lesser GPUs, and your PC build-up won’t be powerful enough if your aims are very high. However, as the trend for compact PCs is growing, manufacturers are focusing more on bringing out space-efficient hardware that should keep things rolling.
Less interior space also means there will be less potential space on the motherboard. So you won’t be able to install as many RAM modules or other drives. Other than that, there will also be lesser expansion slots, and you won’t be able to equip it to the fullest.
With all that said, small ATX cases are still outstanding, and most of them provide features that will allow you to build your PC to the best. So, if you have a plan to manage heating problems, and you’re mentally ready to lose out on some non-essential hardware, then the compact cases will be great for you.
