1,000 Media center computer.

[tpgman]

I'm building a computer that I plan on hooking up to a 42 inch HDTV. My (wonderful) fiance is giving me a 1,500 price limit, including the TV and sound system.
It will mostly be used for gaming and streaming movies.

Here is the TV and speaker system

I wanted to get a remote or something but I had no idea where to start with that, so if you have any advice on that as well, it would be greatly appreciated.

If you want a silent case, here's a suggestion:

Fractal Design Define R4

You might want to get a better motherboard and aftermarket cooler if you're planning to overclock the processor.

For a media center PC I wouldn't consider a full tower. Try a build similar to this:

I have the older version of this case and it looks like it blends in well with a home theater system.
