All cards with techically 'work' with a dell. is it a normal Inspiron 530 or one of them small ones (with the narrow case) because you can run into some problems getting a larger card to fit.
However if you say you want low end since he doesn't care much that 2400 should be fine. Small and will fit in anywhere and work on the weak power supply Dell likely put in there.
yeah i told me brother to get the big one for that reason thanks i think im going to go for this.
