To come close, Tomshardware had to build it. Here's the article.

But your post asks for more and a pre-built on top of that.

I am hoping that I could get a recommendation for a budget desktop that could be used for moderate gaming. I really appreciate any help that you all could provide.
Here is what I am looking for:
Price range: I am aiming for something around the $500 range. I could maybe go as high as $700 if it would result in a better overall return on the investment, but I couldn't spend any more than that.
OS: I would want either a Windows 7 or 8 system. I have a slight preference for 8, simply because it is newer and would be supported for a longer period, but that is not a deal breaker for me either way, since I prefer the 7 user interface with a mouse and keyboard. (No, I am not interested in a Mac, thank you.)
Hard drive: 1 TB would be nice, but I could realistically get by with as little as 500 GB, if it meant I could get more processing power. Anything larger than a terabyte or two would probably go to waste on me.
Usage: I would use the computer for a work, general home use, and gaming. I am the type to keep my computer on 24/7 (so that I can access the desktop remotely when I need to), so good cooling is useful. I play a lot of browser based games, as well as Blizzard games (Diablo 3, and Starcraft 2), I got Skyrim last year, but my old setup (from 2009) was not able to run it. I do not need something top of the line, just a computer that could run Skyrim or similar game at an OK framerate. I am not an early adopter, so I have no problem waiting a few years to play a game. However, it would be nice if I could find a system that could last me another 4-5 years of such use with minimal upgrades.
Chassis: I really couldn't care less about the style of the chassis, beyond preferring an upright tower to a more horizontal shape. But even that is not really a big deal. 6+ USP ports would be good, as well as HDMI output, Ethernet, and any other standard ports. But lights and sleek design would do nothing for me, as the computer would just sit under a desk all the time. A DVD drive would be preferred though, or at least the space to install one later. I'm also not terribly concerned with noise. I am used to the fans whirring away, and I use headphones when I play games.
Manufacturer: I am looking for a prebuilt system. I have no experience building a computer from scratch, and I am not really interested in doing so this time. I could upgrade a component if I needed to, but I would rather have a company to call for customer service with some sort of limited warranty than to save a few bucks doing it myself. That being said, I really don't care very much who the manufacturer is, as long as it has good components for a great price.
Thanks in advance for your help.
