suggestions or known problems?

[devster]

Within the next few weeks I have to start telecommuting so I figured it was time to upgrade the old clunker. These are the parts I'm planning to buy, if anyone knows of any problems with this hardware or has some suggestions, your comments are appreciated. My spending limit is $2000, but I want a machine that'll last me through college. I already have speakers and a decent monitor.

Other than for work, this machine will mainly be used for playing games, audio editing, and low-end video editing.
