Where can one find parts to build a personal computer?

I recommend Best Buy because they have constant price reductions and are very knowledgable.:)

Improved: I agree, But Best Buy is quite expensive, And the only GOOD price reductions are on the display products. So If anything, It depends on why you would need computer parts, For Gaming? Buisness? Or just Surfing? I'd suggest Tiger Direct (http://www.tigerdirect.com/), Amazon, or New Egg (http://www.newegg.com/) The reasons why I give you these sites Is because of the convenience, I have never been screwed over by them, And although they're prices may be high, It's because they're quality, So, It's really up to you wether you want to go and shop for chinsy computer parts at Best Buy, OR buy extremely quality parts at Tiger Direct, or NewEgg. Remember, Don't just buy random parts, Just because someone says you need them, Ex: If someone says you need a new Graphics Card, Don't just buy the X43Q Xtreme Graphics Card because it has the Words "Graphics Card". Make sure you know what your parts will be used for, If you want a computer for Gaming, Then Get gaming parts etc. I hope I helped a bit...
