I am thinking about buying a optiplex 6x 280 tower from dell. It doesn't come with a video or sound cards. what are the best ones for this type of tower? it will have 160g harddrive and 2000 ram. thanks
You can't really go over the top as you are limited by the case cooling and power supply. What are you using the system for?
