  2. COMPUTER CASING

  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. Type Of Casing • 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)

  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.
