Go through the Dell site to get an idea. Not only are their prices reasonable for what you get, but the reviews are always high, especially on the service. When I was getting set up, I had many talks with their technical help, 99% connected to my ignorance and not to any failings on the part of their equipment. Their sale bundles are very good and save you a lot. I priced out one package item by item at several places and came out over 30% more than their package price. Any package can be upgraded, drives, sound cards, etc. to get just the setup you want.
They upgrade their production line frequently, and in making the setup, the only problem I had was plugging in the speaker system- they had moved the connection sockets, but that was handled by a phone call.
