2nd Red Ring of Death - Oh the pain!

For a few weeks now I've been getting random RRODs which seem to clear after rebooting a dozen or so times. I went on the Xbox support site and requested a coffin shortly after Halo 3 came out. I was playing The Orange Box and PGR4 yesterday and now the graphics have a funky shading thing going on. This morning RROD all the time. Doorbell rang - there was the coffin.

So, timing is right I suppose. I don't think I will be able to wait 4-6 weeks. Luckily I have a spare 360 although I didn't want to break it open. Who am I kidding - that will be opened by noon.
