Twister2,
best thing to do is post your money limit and an idea of what all you need and what all you might be reusing ( think you posted you would reuse your monitor, speakers?, how about your keyboard & mouse? )
this would help others help you in finding you a good buy or parts for a good build perhaps? if you are into building your own ( isn't that hard to do, and is a good learning experience )
hope this helps
