Maybe it's just luck, but I always seemed to have a better time getting things (hardware or software) working on the 3000T. Plus it's a C= case. The 4000T's case is pretty lame. Built-in scandoubler is nice, too.
The A3000T case wins the award for the HEAVIEST case of any home computer ever produced. I am sure four of them could be used as jack stands to support the weight of most cars if you put one at each corner. It amazes me how heavy my A3000T is compared to my A4000T. Having a bad back makes me not want to have to move it around if I don't have to.
