Computer Hardware Labs
Building a Custom Computer System
You work in a computer store building computers. Customers ask you to recommend the components of their new computers that you will then build. Please recommend computers for two of the following four customers using this format:
Type of Component Brand & Model Place of purchase Price
Example:
DVD Player Sony x16 / x40 Future Shop $116
This DVD player was chosen because of Sony’s record of reliability. It is a fast drive and the price is within budget. PC Magazine states that “the Sony DVD player is the best buy” in their July issue.
Build Easy PC is a very good resource to help you choose components and guides you on how to build a computer.
These sites are good places to find prices on components:
NCIX - Atic - Tiger Direct - New Egg - Future Shop - or use any other site as long as you site your source with a link
Choose 2 of the following system types and make sure your entire system falls within the budget
1. Home user:
Budget: $500
“I use my computer mainly for the Internet, e-mail, and word processing. I would like to be able to edit and print photos with my new digital camera. My children like to play games but I’m not worried if they cannot play the newest games.”
2. Entertainment Center:
Budget: $800
“My computer is my entertainment center. I do not have a TV or a stereo. I want to be able to play music and DVD movies on my computer with full surround sound. I also want to burn CDS of music to play on my car stereo.”
3. Multi-Media Developer:
Budget: $1200
“I develop multi-media applications for a living including: CD-ROMs, Web Cites, Brochures, Videos, Music, and Posters. I need to run Adobe Photoshop, Illustrator, Premier, and PageMaker, as well as Macromedia’s web development package. Often I need to run several applications at the same time. I must scan client’s photos and print high quality samples for them. I will also have to burn copies of CD-ROMs, DVDs, and files for the print house.”
4. Gamer:
Budget: Unlimited
“I want the ultimate gaming machine. Money is no object since I made a fortune buying and selling dot com stock before the bottom dropped out of the market. I want to be able to play the latest games from flight simulations to first person shooters. I also enjoy playing older arcade games. I want great sound and I want joysticks for the different types of games I play. I have a different computer for office tasks so this machine will be strictly for fun.”
Each Computer Should Include At Least the Following Items:
Motherboard
CPU
RAM
Hard Drive
Optical Drives
Case / Power Supply
Video Card
Sound Card / Onboard Sound
Network Card / Onboard Network
