BUILDING A PERFECT PC!

The COMP129 project is designed to help you apply what you are learning each week using current hardware and software options to build a PC that meets a specific purpose. Although your Final Project is due in Week 7, you will begin working in Week 1 and continue adding components to your computer in each week of the class. Start by selecting the purpose of your computer and a budget. Then you can work each week to select components for your PC based on what you are learning in your class activities. Download the project deliverable template and create a spreadsheet in Week 1. (Remember, you will be turning in these two files in Week 7.) Build on these during the term as you work on building your perfect PC.

Guidelines

Plan to build your perfect PC. (Remember, you are to select each part of the computer. No kits are allowed. No prebuilt computing devices are allowed. This project is designed to help you apply what you are learning each week using current hardware and software options.) Use the lab project template to turn in your project questions. Attach an Excel spreadsheet that includes the major components, specifications, parts, vendors, pricing, and total cost as outlined below. (You can add additional rows and columns to the Excel template if you want to add more than the minimum in your completed computer build).

1. Plan the purpose of your computer. (Remember, Chapter 10 in your textbook will give you some ideas on what you might select as a purpose.)
2. Preplan a price range and try to stick to it. (Were you able to stick to your budget? Why or why not?)
3. List all major components in your spreadsheet template. (Include at least the motherboard, processor power, memory, drives, and monitor size. Add to this list as needed).
4. Determine all necessary parts to buy. (Include at least the case, expansion cards, NIC, and keyboard. Add to this list as needed.)
5. Include OS and software.
6. Update an Excel spreadsheet with all specifications and parts.
7. Price parts from two locations. You may use brick-and-mortar stores in your area, such as TigerDirect, and online sellers, such as.newegg.com/”>newegg.comor.tigerdirect.com/”>http://www.tigerdirect.com/. You can do all of your .comparison shopping online, if you desire. (You will be adding in the prices from these two locations as separate columns in your spreadsheet. See Item 8 below.)
8. Update your spreadsheet with the seller’s name, prices, and totals. (Make sure you add the vendor, price, and total for all the items you select, as well as the total for the computer as a whole.)
9. Write a 4–5-paragraph report on your learning and experiences in completing this project. Make sure to include an introduction, two to three paragraphs about the project, and a conclusion for full credit on this part of the assignment. Remember, this portion of the project is worth 10 points, so make sure you are thorough and complete in your essay.
