I created this thread for exactly this type of question, so please make use of it.
Anyway, down to the nitty gritty. The most important question (what do you want to do with your machine?) has already been answered, so the next most important question is: 'What is your budget?' All the parts I listed above are competitively priced and should be well within a frugal gamer's spending limit, but it helps to have a number to build around.
