If you have around a $300 to $400 budget, you can get away with decent specs with bundles on Newegg that have decent quad cores and cost $240.

By the time you add a CPU, ram, hard drive, motherboard, PSU, Rom drive, Case Media Card reader, case, OS, keyboard, mouse, and speakers that a typical budget pc comes with, you will end up spending an extra 100 to 150 dollars more building a budget system yourself than to buy a prebuilt budget system with the same specs.
