Great to see AMD getting its dual-core CPUs to market. It's probably going to be a year or so until I upgrade (my current 1.7GHZ P4 still satisfies my needs), but when I do...DIY may be the way I end up going. And AMD is lookin mighty fine to me.
This case may be the perfect match for dual-core AMDs:
