BleepingComputer.com: Will pay for upgrade help on computer

I have decided to upgrade my computer to be able to handle media streaming to use with my xbox360 and laptop. The only problem is that i really dont no where to start and being that im in Argentina right now im pretty much on my own with it. Here is my current configuration a Gateway GM5632e. I have also installed Windows 7RC 64bit. Both 500gb hard drives are filled with movies and music so im thinking of replacing one of the hard drives with a 1.5TB one and also adding an eSATA port. Since I dont speak the language here, I cant just take it to someone. I have a limited knowledge about computers so if anyone is willing to assist me I will be more than happy to compensate them. Also if anyone has any other modification suggestions that should be considered I will greatly appreciate it. My budget is between $400-$600 Keep in mind that I am probably going to have to order everything online. Thanks

Hi! I don't know much about gaming, but before you get a 1.5 tb hard drive, look at this.
