So I, like many, am anxiously awaiting my new iMac (3.06, 4850). I just ordered tuesday but i noticed something on my order details online that i dont know what it means. yesterday when i checked the details of my order, under imac 24", it said custom configuration, then you could click it to see the specs. today it says imac 24'/SD and there is no "custom configuration" under it. whats goin on, im not freakin out but curious as to why this change occured. anyone else ever notice this or know what it means? i cant remember whether the /SD was always there or not either.
