Wow, I had totally forgotten the "eMac". I think it was the entry level Mac for a couple of years, but only sold to schools. I think it was the only all-in-one Mac to still use a CRT display after the iMac had gone LCD.
... Aha, right. It was also sold to the general public later, though. Until LCDs really dropped in price, they still needed a CRT model for entry level pricing.
