Dell Inspiron 530 vs Vostro 200 (same thing?)

As the subject line suggests, I am just wondering if they are, technically, the same. Say if I would build both with the same user custom stuff I can throw inside through Dell's website would the end products perform equally. I'm asking this because there are some good deals this weekend on Vostro systems, and looking at side by side specs they seem like the same product, just a different case.

I know one of the differences is that you can't use Dell Credit for "Small Business" computers which is fine since I don't plan to use it. But thats finance wise and not hardware.

Finally I know that there is little or no bloatware on Vostros as well.

Anything else?
