Great, now a couple of more questions...you said that you might use it to play a game every now and then. A video card can be quite expensive, and in order to play current release games you would need a current video card, so my question is what games are you wanting to play, if you could be as specific as possible that would help me figure out what type of video card you will need. Realize that your main expense in this unit will be the mother board, memory, and the video card and of course your processor.
The second question and most improtant is what Operating System are you going to run. If you stay with Windows XP then we can make this work, but if you want to go to Vista then....well you may not be able to run it to the level you want with the funds you have available.
Third question, do you have your monitor or does that need to be a part of the $700's
