This document discusses computer casing and hardware. It defines computer casing as the box-like case that contains a computer's electronic components. It describes the main types of casings as desktop, mini tower, mid-size tower, and full-size tower. Each type is defined and their advantages/disadvantages listed. The parts of a computer case are identified as the front panel, back panel, and internal parts. Three factors that influence computer case design are identified as ergonomics, expansion capabilities, and cooling.

3. OBJECTIVE
By the end of this topic, student should be
able to:
- Define computer casing.
- Determine type of computer casing.
- List down the example for each part of
computer case.
- List down three factors influenced the
computer case design.

4. Casing also called system is a box like
case that contains electronic components
of the computer.
Type of casing design :
1. Desktop
2. Tower (Mini Tower, Mid Size
Tower, Full Size Tower)
Type Of Casing

5. DESKTOP
Desktop is designed
so that the system
unit fit entirely
on/under a desk
table.
In some models, the
monitor sits on top of
system unit, which is
placed on top of the
desk.

6. Desktop
Advantages:
Excellent desk computer.
Space
Disadvantages:
Difficult to upgrade
Does not really work on the floor.
Recommendations:
Excellent choice for a business and home user
computer.

7. TOWER
 Most of the casing
now using a tower
style.
 This design enables
the system unit to sit
on the floor vertically.

8. MINI TOWER
Advantages:
Excellent size which can be placed on top
or below of a computer desk.
Disadvantages:
While this case does offer upgradability, it
can be filled up much faster than the Mid-
Sized tower.
Recommendations:
Great PC for end-users and small
businesses.

9. MID-SIZE TOWER
 Advantages:
Excellent case which can fit below and on top of
your computer desk.
Plenty of expandability for new devices for
businesses, end-users, and advanced users.
Disadvantages:
None
Recommendations:
This case is an excellent choice for all users and
businesses.

10. FULL-SIZED TOWER
 Advantages:
Excellent computer for upgradability.
Excellent case for a server machine.
Disadvantages:
Cost is going to be a lot more than a standard
case.
Generally a large case which cannot be placed
on top or beneath a desk.
Recommendations:
We recommend that this type of case be
purchased by advanced users or users who plan
to have a stand alone machine as a server.
