i dont think u can put a dell in a new case, coz of the holes on the motherboard, i dont think dell like ppl changin the cases on there computers so they change the holes. plus u would have 2 get a new cpu fan, coz the cpu fan on them dell pcs r on the case, and im guessin u can have PC3200 DDR mem in that pc, u should be able 2 buy any old AGP card, i dont no about the new ones coz of the dell PSU.
