It's been a few weeks now and my xbox 360 is still working perfectly.I had the RROD prob and i accidentally fixed it (have no idea how i did it).So i decided to place the xbox360 into an old pc tower case and added some adequate cooling to the cpu/gpu.I can play for hours on end now without any freeze's or rrod's.
Microsoft's next console must be encased in a pc box.I know it's bulky but at least it will last longer.
