What is a good desktop computer to buy?

Question by @>*~Be@ut!ful D!$@$ter~*<@: What is a good desktop computer to buy?
I am looking into purchasing a new desktop computer. I already have the monitor, mouse, keyboard & speakers. So i only need the tower. My limit is probably about $ 500. I need something with lots of memory, and pretty fast. This will be used mainly for business which involves a lot of pictures & movies & music. Nothing refurbished or used. Brand new. I would like to go into a store and purchase it, not just online. I like to see what I buy before I pay for it. Anyway…any suggestions?
