I picked up an Xbox 360 at a garage sale for $5, since it had the red ring. I was hoping I could get MS to repair it, but it is out of warranty. I'm looking at repairing it myself to keep as a spare, or to sell. It would also be good practice if I ever have to repair my 360.

I was wondering if any of you know of a good guide for this? I was looking at Llamma's Xbox 360 3RLOD X-Clamp Fix Tutorial. I'm trying to figure out what is the best to follow.
