I love the 3000, it was the fastest design memory wise of all the big boxes(well 3000t was as good), but lets also not forget the ridiculous rom tower for rev 7 boards also 
ok looking case but not my favorite to work on by a long shot. the 4000 case was not as pretty but way more practicle.
I love both the 3000 and 4000. Each have their advantages...
I actually prefer working on the 3000D over the 4000D. I think I may be in the minority here.
