One of the basic elements of a desktop computer is the case. There are a wide variety of forms, sizes and exclusive designs. The price will increase depending on how easy is to mount the inner components, how resistant it is or how cool the design is.

How To Choose The Appropriate Case

Case Sizes

There are several standard sizes, each of them adapted specifically to one or another requirement. Here I will list only the commonly used sizes used to build Gaming PCs:

  • Full Tower (E-ATX). Lots of expansion options and space. This kind of cases are used for hardcore gamers, those who need multiple graphics cards, multiple hard drives, lots of RAM and free space to install triple radiators, gigantic heat sinks and 230mm case fans.
  • Mid Tower (ATX). It was the standard size until we got the Micro ATX. It has enough space to accommodate two graphics cards with a proper refrigeration.
  • Mini Tower (Micro ATX). This size has been replacing the mid-tower in the past years and now is the common size for most of the users. It is usually cheaper than bigger sizes cases and supports Micro ATX motherboards, which are the most common motherboard size.
  • Small Form Factor or SFF (Mini-ITX). Usually used as HTPC (Home Theater PC) because of the saving space benefits.
Cases Sizes And Common Features
MotherboardsMini-ITXUp to Micro ATXUp to Micro ATXUp to EATX
5.25” Drive Bays11 to 22 to 53 to 6
3.5” Drive Bays1 to 34 to 66 to 86 to 13
2.5” Drive Bays0 to 40 to 40 to 100 to 10
Expansion Slots247 to 87 to 10
Graphic Cards11 to 22 to 33 to 4
Case Fans1 to 32 to 43 to 95 to 10


  • Put your case in a fresh and ventilated place. Otherwise, you will be covering the case’s air outputs and that will overheat your CPU, GPU and PSU.
  • Always double check how many fans are included in the case you want to buy. Sometimes, usually in the cheaper models, the manufacturer images can be tricky.
  • Clean up the case inside regularly. The dust is accumulated in all the case’s fans and CPU’s and GPU’s ones. If you don’t clean them, they will move less air and therefore the case inner temperature will get higher.
  • Do not buy cases for less than $60 with power supplies included. Those power supplies will be probably cheap and of poor quality.
