Good Water Cooling Case?

I'm building a PC which will sit next to my HDTV. Primary use for this machine will be gaming, and Blu-Ray, with office functionality in a secondary role.

To that end, I'm considering water cooling as it is quieter and provides better performance. I'd appreciate any suggestions for a good case to use, which will allow me to cut a template in the top for the radiator at a later date. I've looked at the Corsair Obsidian, and a few Silverstone models, and while these are undoubtedly great cases, I wish I knew if it was worth it to be spending over $200 for just a case. If I can get by with something cheap (but still solid) I'd like to do that.

I've beard of some people getting he antec 300 or 900 and mountin a rad under the giant 200 mm fan sitting on top of he case


I also have the antec 900 and the loudest thing in my case is the graphics card, with the 200 mm on full and the 120 mm exhaust fan on medium

What about it
