Don't go dell!

They source their components as cheaply as possible. And you are forced to buy "dell" upgrades most of the time if you want to expand.
Dell make computers for "home users" and office workers, computers that are essentially disposable for users that don't demand high performance.
You can get souped up one's but, you would be better off going elsewhere.

If you want an audio pc check out carillion - they make computers specifically for the purpose.
