Mine was a completely standard 2400 -- the only upgrade was RAM, and that was at purchase (back in 98). It glodded after about three years heavy use as my main computer, initially always going down when I was on the internet (making me wonder if there were heat issues). Sent it into Apple who replaced the motherboard. It was fine until just out of repair warrantee, then glodded again... :( Now I just use it for fun and never on the internet. Nicole
