A floppy disk drive allows for the usage 1.44mb floppy disks. It is also used for diagnostics and data recovery. Therefore it is recommended to have a Floppy Disk Drive on your PC.

Memory Card reader:

A memory card reader is a device that allows you to connect flash memory and other such memory to a computer for fast access and modification. If you have a digital camera you may wish to purchase a memory card reader to transfer your photos quickly and without having to use a program to do so.

Memory card readers can normally read the following media types:

• MS/MS-PRO/MS-DUO/MS-PRO DUO/ (Memory Stick)

• Secure Digital (SD)/MINI SD*/MMC/RS-MMC*

• CF1/CF2 (Compact Flash 1 & 2)/MD (Micro Drive)

• SMC

Case:

This is where the motherboard, CPU, the Power Supply Unit and Hard Drives of the computer is housed. The 3 basic types: Tower (for servers and high-end computers), Midi-tower (for most common uses), Desktop (where the case resides under the monitor or on its side) or Shuttle (a mini case which can be carried around and is meant to be portable)

Power Supply (PSU):

A PSU is the Power Supply Unit for your computer. The average PSU nowadays ranges from 350W up to and above 600W. If you are ordering a powerful computer, for example a processor of 3.2ghz or above, we seriously recommend you choose a silent power supply unit with advanced CPU cooling fan. They may add a small amount to you order, but it will make your computer super quiet instead of fairly noisy.

Each component in your computer uses a proportion of your power supply's power output capabilities. As a rough guide, the following compoenents use:

As you can see, the minimum power supply you should have in a computer is approx. 350W by doing a little maths, but if you're willing to spend that bit extra, you can get a silent power supply with a silent cooling system.
