My Lab Report for CSC103: PC DEMOLITION!

Ariel Weeks


  1. Take apart a PC
  2. If possible take some of the parts apart
  3. Take notes, and or size of certain elements
  4. Take pictures of the important parts inside of a computer
  5. Recognize the different parts by their specific name

Computer: Make & Model

DELL Optiplex GX270

Visible Parts

  • CD/DVD Drive
  • Power Supply
  • Cables
  • Hard Drive
  • Motherboard
  • Internal Speaker
  • Padlock Ring
  • Heat Sink and Blower Assembly

Parts: Looking Further Inside The Computer

CD/DVD Burner Drive


The CD/DVD drive was connected to the cover of the computer. It was standing next to the hard drive and across from the motherboard. It also had cables connected to it leading to the motherboard. It was easy to pull out because it had green tabs to pull.


  • Download Software
  • Video Games
  • Watch DVDs for Movies
  • Play CDs for Music
  • Burn CDs
  • Burn DVDs


Power Supply


The power supply is the larger box that sits inside of the computer next to the motherboard. It is what gets connected to an electrical outlet and provides the power to all the different parts inside of the computer. It has a fan connected to it to keep it from overheating.

Max. Output Power

  • 210w




The cables are connected all throughout the computer. They provide the power for all of the functions throughout the computer to work properly.

Hard Drive


The hard drive was found connected to the cover of the computer. It was next to the CD/DVD drive and across from the power supply.

  • According to WikiAnswers, "A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile, they retain the data even when they do not have power." (in WikiAnswers. Retrieved Feb. 21 2012, from http://wiki.answers.com/Q/What_is_the_function_of_a_hard_disk).
  • It holds up to 40.0 GB of memory




The motherboard takes up most of the space on the bottom of the inside of the computer. This is the central unit in the computer. It provides connectors for other parts of the computer and brings everything together. I guess you could say, "it's the glue that hold everything together."

  • The small line that you see located all over the motherboard are very fine wires where bits of information fly.

Internal Speaker

The speak was connected to the cover of the computer, right in front of the hard drive. This speaker creates waveforms and allows audio to be heard from the computer. It's great for gaming and music!

Padlock Ring

This ring in connected directly into the computer on the back and comes out just enough so you can stick a lock through in order to protect you computer.

Heat Sink and Blower Assembly


The heat sink and blower assembly are connected to the bottom of the inside of the computer. This setup sits right on top of the processor. This is used for what is called, "Computer cooling." Since the computer's components generate so much heat, it creates "waste heat." The heat sink and blower assembly work to take that excess out to the computer can maintain an operating temperature. It work to cool down the computer's system.



The processor is located under the heat sink and blower assembly. It is known as the CPU (central processing unit). The processor is known as the, "brain" of the computer, because it is where calculations are done inside of the computer. It also follows through with instructions for a computer program.

  • This specific processor is an INTEL

Information of the Back of the Processor

  • Pentium 4
  • 2.80GHZ/512/800
  • 3420A336

The RAM (random access memory) was found on the motherboard. RAM is computer memory.

  • 2X 256MB of Memory




The crystals are located directly in the motherboard. This is covered in metal and it lets the processor know how fast it can go by generating a frequency.



The battery is located directly on the mother board like the crystals. The battery hold information even after the computer is turned off. It holds things like the date and time, so when you shut down your computer and reboot it you time and date should still be correct. If it's not, then you should look into changing this battery.

During our lab session, we took apart a DELL Optiplex GX270. We took pictures and notes and studied the different parts inside of the computer. We also learned how the parts play as an important element of the computer, and there were also helpers around to help assist us with any questions we had and they were quite resourceful.

Me & Aubrie: YAY, We did it!!!
