Never heard of that brand of computer before. But reading through the hardware listed, it sounds pretty dated.
The link above is to the 420 series from Dell. They are about $300 more, but you get what you pay for. You'll also get about a year free of customer service from Dell.
If you just want to pay some money and 'poof' have a decent system you will have to pay a premium. If you cut corners, there is no telling what will be in that box they send you. Lastly, if your primary concern is cost then I emplor you to look into building your own system. It's really not that hard to do, putting it together is just as easy as charging your cell phone in most cases. And you will get alot of bang for your buck, but I realize it is not for everyone.
