I just don't know. After looking at the specs, I can't say that I'd be all that interested in switching from ATX anytime soon. I actually wouldn't want to go smaller unless other peripherals such as vid cards and other AGP and PCI cards get smaller as well. I like knowing that I have alot of expansion capability even if I never actually use it to the fullest extent. I agree, "If it ain't broke (or out classed), don't fix it!" We certainly don't want our computers' nads "Fixed"!
