P.D. I am glad we were able to help you find a good replacement for your Dell Computer. I think that in general the HP Business Desktop Pro line seems pretty solid, and well priced. In particular, the system you bought with 4GB of RAM, a 500GB hard disk, and a quad core processor should work well for you for a long, long, time.
Glad we were able to help you out.
