Ulitmate Buying Tips

There are some things that need to be cleared whenever you buy a good case . This ultimate buying tips will help you to choose the perfect case for your gaming build.

Supported Format Of Motherboard

  • The most common format is the standard ATX, which corresponds to medium and large towers and the one that is recommended. Indeed, this format gives the largest choice of motherboards, as well as many possibilities of extension, and also many settings of the Bios, especially for overclocking.

  • The micro-ATX format is quite used, it keeps ATX features in a smaller format (244X244 mm) and at a lower cost, with a PCI-Express x16 bus and PCI-Express x4 or x1 ports and PCI. Although there is less choice of motherboards and less opportunities in the Bios in general, this format is possible for a desktop PC or even ‘gamer’ is the recommended format for a compact box, mini-tower or barebone.

  • The mini-ITX format is making a comeback, mainly for Home Theater PCs. It is not really suitable for a PC “gamer”.

Build’s Components

If you already bought your pc parts and planning to buy a case, remember to check CPU height, PSU size and motherboard type before buying a case, otherwise you will have to return your product if it was not compatible with your pc parts

Case Build Quality

If you are looking for a perfectly good looking case but ignoring the case quality, then this is the biggest fault that you are doing. Always check build quality before buying. All aluminum and steel case is best with the best chassis for durability.


If you are planning to buy a case for one time, remember to check that case has enough space to expand your system in the future .more PCI slots and drive bays will allow you to add some components to increase your pc perform.

Air Flow

Most of the cases have a weak airflow system in a case that may end up with heat up issues. Remember to pick the case with the best airflow and which can support more fans and radiators for smooth gaming.

To avoid the risk of overheating and damage to the equipment, the housing must be well ventilated and well ventilated.

A gaming case must include at least 2 fans.  There must be at least one fan at the back of the housing, its role is to evacuate the hot air to the outside. As well as an additional suction fan at the front allows to maximize the flow of air and to better cool the hard disks. 

Some enclosures are designed to eliminate ventilation noise as much as possible. This is the case for models whose panels are covered with an acoustic reduction coating.
Other information, the volumetry of the housing also influences its heat dissipation. (A large-format tower case will take longer to fill with hot air).

Dust Filters

As the most ventilated PCs, and therefore the most powerful, swallow large amounts of air to cool the components, they also suck a lot of dust, various particles, and even hair. Ultimately, these elements will reduce the effectiveness of gills and ventilation. When the inside of the PC is clogged, the fans force and make even more noise. That’s why the presence of easily accessible dust filters for removing and cleaning them is important for gaming PCs.

Cable Management

Remember to chose which have cut out spaces for cable management, so your case looks clean from inside.
