Some Things to Consider
Sean goes over the features of an ATX standard mid-tower computer case. It features a fan on the side, another fan on the back, a third fan that is part of the case's power supply, seven slot bays for PCI cards and eight drive bays.
It's important to consider air flow when choosing a computer case. Ideally, you want to choose a case that draws air in from a low area, pulls it through the hardware and out through a high area.
A standard case such as the ATX in the video can range anywhere from $60 to $80. You might even be able to find one for as little as $20 or $30 from a second-hand store. A more expensive case may come equipped with larger fans and air filters.
