Please take a look at the link

and sort by ^Price .

In the future if i want to upgrade, can i upgrade with any product like from newegg.com or only can upgrade from dell products.?

And is this a good deal ?
Or should I buy the spec from newegg.com and build it myself and save money?

I am using it to mainly watch videos from youtube, google, CNN. I have cable internet.

Thanks in advance
Oh, and in Stockrooms tab select > Inspiron 530s then sort by ^Price.
