i concur with everything that was said here. one more thing, do you have case fans? if the case doesn't come with em, you might want to add 2 80mm vantec stealth fans to the mix, or if you're overclocking, get something more powerful than them, and/or more of em
* Usually on high-end Athlon XP systems, Corsair XMS is found. I would choose it for this build. Or <A HREF="http://store.yahoo.com/memx/gn256pc3200.html" target="_new">TwinMos memory with winbond chips</A> if you want to keep costs down.
