A computer case, also known as a computer chassis, tower, system unit, cabinet, base unit, or simply case, is the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse).

The case or chassis is often overlooked when buying a new computer. Below are some things to think about regarding the case.

  • Do you want a desktop or tower case?
  • Will the case fit on top of or below your desk?
  • Will the drives be accessible or will they be positioned the way you want them to be positioned?
  • Does the case support the standards of motherboards, for example, the ATX motherboard standard? This is important if you want to upgrade the computer in the future.

Hard drive

When purchasing a hard drive, it is important to understand and verify the hard drive is suitable for your uses and has or does not have the options you may or may not need. The hard drive will be the destination of all your files and information. Make sure you get a hard drive with plenty of available space and runs at speeds that don’t slow the overall computer down.

There are two types of Hard Drive. Solid State Drive (SSD) and Hard Disk Drive (HDD). So which of the two is the better choice, an SSD or HDD? There’s no straight-forward answer to this question; each buyer has different needs and you have to evaluate the decision based on those needs, your preferences, and of course budget. Even though the price of SSDs has been falling, the price per gigabyte advantage is still strongly with HDDs. Yet, if performance and fast bootup is your primary consideration and money is secondary, then SSD is the way to go.
