you have already made a big mistake by getting a duron. get an XP CPU instead, or at the very least get an athlon, anything is better than a duron or deleron. all your other nice hardware will be a waste of money on a duron or celeron.
to avoid static discharge touch the metal part of the case while the computer is off with the power cord still plugged in the wall and unplug the power cord from the wall outlet.
don't move around too much on carpet. i always keep some part of me touching the case like my elbow. if you need to go somewhere else plug the cord back in and do it again. static wristbands are too much of a hassle.
with wrist band you still neeed to do the same thing with the cord. the cord is to ground yourself so the static from your body can go somewhere else. i have never fried anything doing it this way
did i say "deleron"? i meant celeron....... the "deleron" are the higher end processors, hehe
